Color Variations
For 78 colors as listed above, rgb.txt offers four variants ‘color 1’, ‘color 2’, ‘color 3’, and ‘color 4’, with ‘color 1’ corresponding to ‘color’, so e.g. ‘Snow 1’ is the same as ‘Snow’. These variations are neither supported by popular browsers nor adopted by W3C standards.
The formulae used to determine the RGB values for these variations appear to be somewhere near
color 2 := color × 93.2%color 3 := color × 80.4%color 4 := color × 54.8%
Examples:
- 205.2 = 255 × 80.4/100 and 192.96 = 240 × 80.4/100 explain ‘Ivory 3’ (205, 205, 196) based on ‘Ivory’ (255, 255, 240) .
- 139.74 = 255 × 54.8/100 and 131.52 = 240 × 54.8/100 are close to ‘Azure 4’ (131, 139, 139) based on ‘Azure’ (240, 255, 255) .
- 237.66 = 255 × 93.2/100 yields ‘Yellow 2’ (238, 238, 0) based on ‘Yellow’ (255, 255, 0) .

Famous quotes containing the words color and/or variations:
“‘Twas mercy brought me from my Pagan land,
Taught my benighted soul to understand
That there’s a God, that there’s a Saviour too:
Once I redemption neither sought nor knew.
Some view our sable race with scornful eye,
“Their color is a diabolic die.”
Remember, Christians, Negroes, black as Cain,
May be refin’d, and join th’ angelic train.”
—Phillis Wheatley (c. 1753–1784)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
