Concentric Numbers of the RCW.
|
|
The dots on the colorwheel locate different pigments on 10 different value concentric rings. There are 36 wedges for 36 colors and 10 blocks to dark neutral in each color.
#1.0.9 is the coolest yellow in the yellow arc, a tint of Indian yellow transparent could be #1.00 to #1.09 (two digits for tints) #1.0 is the Pure Yellow wedge with 10 graduated values getting darker below it, there are 36 color wedges in all, Color #1, yellow, has five different pigment color values located in it, 00, 0, 3, 6 and 10 all have pigments in them. Brown is the darkest intensity of Yellow. Mix this low intensity yellow with it's opposite color Ultramarine blue for a neutral dark. THIS IS HOW AND WHY THE RCW WORKS.
Element Color = Crystal and Chemical Colors = Pigment Color They all become dark on the same color path. While painting, darks should be made to match nature by mixing in the opposite complementary color and not by adding black pigments. These same color pigments are used in all media.
This RCW 36 colorwheel has brand pigment names and generic Chemical Class names.
It also includes the pigment chemical names in these Chemical Classes, and the Color Index Name, and the Color Index Number. . Each brand name pigment is a chosen color made from one or more Chemical Classes in combination. Each Chemical Class color travels on a graduated path changing hue and... (sometimes) Pigment Color and Color Index number as it moves. The PC number itself also has a graduated path of different related colors. Different brands, different names, same color.. or close. You have to find the right brand color, start with the Chemical Class color. Daniel Smith did a good job, so did Grumbacher. No one brand has all the best pigment colors and there is no standard for the names they choose to call them. Example.. From the element Copper we get Copper Phthalocyanine as a Chemical Class with a path from green PG36 with chlorine and bromine to PG7 just chlorine to Cyan PB15. PB15 has a path from cyan to a transparent ultramarine/blue blue hue at PB15:6, like the crystal Iceland Spar.
PB15.1 has a magenta cast, PB15.3 is pure cyan without added magenta. Grumbacher uses PB15.3.
Blue-Violet is between Cyan and Magenta and is Ultramarine Blue in hue. Blue-Violet is a photo industrial color term for the blue filter used to make the yellow printing plate. Blue is opposite yellow. Red, Green and Blue are primary colors on the Light color wheel only.. red, green and blue are the more saturated RGB colors. Red and Blue pigment colors are secondary colors and can be made mixing the pigment primary colors of transparent Yellow and Cyan or transparent Cyan and Magenta. Red pigment is not opposite green pigment, they are both secondary colors capable of being mixed with pigment.
As in the RCW, the same brown to yellow color intensity path of yellow is found in both element crystal compounds, and class chemical compounds. The elements lead and iron have oxides with similar ranges of color from yellow to brown and red to brown in synthetic chemicals and natural oxides, just like their crystal counterparts. Pigment color oppositions should match the natural color of the element's crystal oppositions. Just as the lead element only makes yellow and blue crystals (and cyan found in Mexico). The RCW matches the chemical class colors with their paths to darker color intensities.
This RCW color wheel, based on the color paths in element crystals, oxides, chemical colors and vegetable colors, it also works with stage lighting. Yellow and red both darken to brown in crystals, natural oxides, chemical class pigments and vegetable colors. Yellow to Brown Elements in Crystal The Chrysoberle crystal with the element Beryllium is the standard yellow to brown transparent crystal. The Citroen Quartz crystal with the element iron includes from yellow to orange to brown. The Chalcopyrite crystal with iron will show colors from, yellow, orange, tan, red and brown. Yellow to Brown Chemical Class Pigments Diarylide Yellow makes these colors. Diarylide Yellow AAA, Diarylide Orange, PO34 Diarylide Red, PR166, Disazo Scarlet Diarylide Brown PY12 brown. Yellow to Brown Chemical Class Pigments Monoazo-Aceoacety Benzimidazolone makes this path of intensity for yellow colors, just like oxides and crystals. Benzimidazolone makes these colors from yellow to brown only, like the Chrysoberle crystal and calcimined lead oxides. Benzimidazolone Yellow H3g, PY154 CI# 11781, yellow to yellow-orange. Benzimidazolone Yellow PY151. Naples Yellow Hue Benzimidazolone Orange, PO62, 11775. D.S = Permanent Orange. Benzimidazolone Orange H5g, PO62. Schmincke = Chrome Orange Benzimidazolone Orange H5g, PO62, Lukas W/C = Helio Genuine Orange. Benzimidazolone Orange HL, PO36, 11780. Benzimidazolone Red, Deep Scarlet, PR175, 12513. Benzimidazolone Carmine, Hf3c, PR176, 12515. Benzimidazolone Brown, Permanent Brown, PBr25, 12510. Benzimidazolone Maroon, Napthamide Maroon, PR171,12512 Benzimidazolone Bordeaux PV32, 12517 Yellow to Brown Oxide Pigments, Opaque and Translucent - Mars chemical compound colors colors are synthetic iron oxides and follow the same color color intensity scale getting darker as iron oxides. Both are matched on the Real Color Wheel. - Old Holland, Iron Oxides, Gold Ocher Light orange side, opaque. Brown Ocher Pale red side. Brown Ocher darker yellow side. Red Ocher dark red side opaque. Brown Ocher Deep is close to Iron Oxide Burnt Umber, translucent. - Talens, Burnt Umber translucent, PR101, Iron Oxide Brown natural. - Blockx, Iron Oxide, Venetian Red natural opaque PR101 - Blocks, Iron Oxide, Italian Earth natural translucent high silica content. - Schmincke, Grumbacher and others, Iron Oxide Raw Sienna, PBr7, translucent high silica content. - Old Holland, Iron oxide natural colors, Gold Ocher PY43, Brown Ocher Pale, - Lefranc Bourgeous, Vandyke Brown, PBr8 Manganese Brown. Yellow to Orange path in Chemical Class pigments -Tereachloroindolinone, which makes Isoindolinone Yellow R, a brown/side Indian Yellow.
Yellow to Green path in Chemical Class pigments
Yellow to Magenta and Yellow to brown Chemical Class pigments.
Cyan darkens to ultramarine blue hue in these transparent crystals and class chemicals... and the sky above us. Crystal compounds Cyan to Blue in color depth. -AZURITE crystal, Cu3[CO3]2[0H]2. COPPER, Standard Azure/Cobalt color, #22.1, [MCCC]. Includes cyan, azure (cobalt blue) and ultramarine blue hue, transparent, translucent and opaque, shows blue in mass. -CALCITE crystals, CaCO3, trigonal crystals, also aggregate and mass, colorless, transparent and translucent. -CALCITE crystals w/COPPER, "Iceland Spar crystal", Cyan, allochromatic, polarizing filter. In this crystal light cyan turns into dark ultramarine blue, like in the the Real Color Wheel. Chemical class compound pigments Cyan to blue.
-PB15 is a primary pigment color, Daniel Smith calls it Manganese Blue Hue instead of Cyan, but it is the same color, marketing. Manganese does make an excellent cyan.
True Transparent Test, the under-tone of any tested pigment will not show lighter on a black paper. Translucent pigments are semi-transparent or semi-opaque, weak opaque colors. Both strong and weak opaque colors all will lighten a black paper, so they are not transparent. -Aureolin, PY40, Potassium Cobaltinitrite, is not transparent as has always been claimed, it's a translucent, a weak opaque. Chemicals can make a transparent dark brown pigment, oxides can make translucent and opaque pigments. Here are the transparent yellow chemical pigments. Indian Yellow can be made with these Chemical Class colors; -Dioxine Yellow Nickel Complex which makes Nickel Dioxine Yellow Br/s PY153 and Green/s PG10F. -Disazo, which makes Dairylide Yellow HR70. -Anthraquinone, which makes Anthrapyrimidine Yellow PY108 and Flavanthrone PY112. -Tetrachloroindolinone, which makes Isoindolinone Yellow R, a brown/side Indian Yellow. Using Transparent Yellow. Indian Yellow is a set of two colors, transparent yellow-orange to yellow PY139, or better PG10F. And transparent yellow-brown to yellow PY153. They both seem to be very, very close. One is a strong yellow to mix with magenta making orange to crimson rose, including bright red, the other is for lower chroma greens and browns. These transparent duel-toned colors mix a lot of greens and reds.
49 pigment colors Clickable on a Real Color Wheel. Don't miss it! New window I wish.. I had a pre-made Purple made with PR122 and PB15, and a transparent Cool Magenta from Cobalt Violet Phosphorous. Also a Rhodamine Y, PR81, translucent or opaque, permanent. Maimeri calls it Garanium Lake and it's bright but fugitive, so Im told, I haven't tested it. Opera is a great magenta but it's just the smallest amount fugitive. I just finished a 10-7-8 to 6-7-9 sun test in my van dashboard. Opera held up very well, only the very lightest tints had any change at all where they seemed to become a little warmer. It was still a good magenta color. Holbine makes a W/C Opera that is more stable but darker. Caution: While Sennelier has the great PR:122, don't buy the cyan PB:15 it has the right name BUT is not the right color, It looks like PB:5.1, a Prussian blue color. They also have a color called "Indian Yellow Substitute" that is not correct, not transparent and a bad choice with the right name.. It contains an opaque PY:1 and PY:83. Test purchased on 12-15-8. Also, D.S. has the right pigment but a lousy name, "New Gamboge" when it should be Indian Yellow Org/side. Gamboge is not as true as cadmium yellow, Indian yellow or tartrazine yellow Pigment Color Numbers MORE, in this window. NEXT PAINTING, Painting Fresco
