Ok... I think I can explain it better than in my previous post...
When we paint something of yellow, we are using a substance that absorbs the blue, and reflects green and red, these 2 colors are what we see. Mixing Yellow and Cyan will create something that reflects red+green and blue+green, so it'll be something like magenta+2x green, But since Cyan absorbs Red and Yellow absorbs blue, the only light reflected is green. They can reflect more of a light than another, for example, mixing 2-magenta + yellow will reflect 2xred and green, which we see as orange. If we mix magenta paint, yellow paint and cyan paint the result is black becouse it's absorbing the 3 colours - About primary colours (Colours that cant be done by mixing any other ones)... in painting, of any kind, are MYB. But the color scheme that the people use to paint can be whatever they want, depending of what colours they want to use (they can even use magenta, green and cyan for cold pictures that don't use red or yellow, for example.) |

Well, it depends what you mean by primary color. RYB is certainly a real color space, but there is a fairly large number of colors that you can't get by combining red, yellow, and blue. In that sense RYB is wrong. But the people who say red and blue are being confused with magenta and cyan have had too much of the happy weed. CMY is a totally different color scheme used often in printing. RYB is the scheme used for painting.
And the question is still answerable regardless of the validity of the color system. I'm sure some of those combinations do have a name. What you can do is find the RYB value of those combinations, convert it to RGB, and look it up as a hex value on google. There are plenty of places such as http://web.njit.edu/~kevin/rgb.txt.html for finding the names of colors. |

I don't know where you guys got your information, but you need a new resource.
The RYB color model is entirely real and is a model of subtractive synthesis that is based on the way pigments combine to form different colors. The primary colors of this model are, in fact, Red, Yellow and Blue. The RGB color space, on the other hand, is a model of addative synthesis that is based on the appearence of light when it reaches the eye. The primary colors of this one are Red, Green and Blue. |

You can use subtraction on the secondary colors to get primary colors again. Cyan+Yellow = Green; Magenta+Yellow = Red; Cyan+Magenta = Blue |

I thought primary colors were colors that couldn't be made by using two different colors and often are used to create other colors when mixed? Green can be made by blue and yellow.
Eidt, didn't see the post above me. |

yeah... the light is composed by red, green and blue... "red yellow and blue" is fake. Paint uses magenta, yellow and cyan becouse it doesn't reflect one of the colours than compose light.
I'm terrible at explaining things... but I know what I mean XD |
| FreeDOS + Posts: 926/1312 |
The primary colors are Red, Green, and Blue. "Red, Yellow, and Blue" is a mistake based off of the fact that paint pigments use the secondary colors, Cyan, Magenta, and Yellow, and two of them (Cyan and Magenta) closely resemble the primaries (Blue and Red). |

You know the three primary colours Red, Yellow and Blue
When you mix two of these you get secondary colours: Orange from Red + Yellow Purple from Red + Blue Green from Yellow + Blue Then, mixing a primary colour with it's neighbo(u)ring secondary colour, you get tertiary colours: Red + Orange = Vermilion Red + Purple = Magenta Yellow + Orange = Marigold Yellow + Green = Chartreuse Blue + Purple = Violet Blue + Green = Aquamarine In a cycle, this would look like: *-> Purple -> Magenta -> Red -> Vermilion -> Orange -> Marigold -> Yellow -> Chartreuse -> Green -> Aquamarine -> Blue ->Violet ->* Does any one know (if there are any) what the 'Quaternary Colo(u)r' names are from mixing any two neighbouring colours in the above cycle, i.e.: Purple + Magenta Magenta + Red Red + Vermilion Vermilion + Orange Orange + Marigold Marigold + Yellow Yellow + Chartreuse Chartreuse + Green Green + Aquamarine Aquamarine + Blue Blue + Violet Violet + Purple? (And can you go further and have Quiquenary, Sexenary, Septenary, Octonary etc. colours? Is there like a list of colours which says whether it's Primary, Sec, Tert, Quat, Quin... that 'uses' the RYB 'system' not the RGB 'system'?) |
