While in return, subtract cyan – magenta – yellow – black and you will get the RGB colors. CMYK colors are subtractive for this very reason that it starts with all colors and when colors are subtracted the outcome is black (see below color swatch, the inside color is white). This is because the colors absorb the light.
To further summarize what has been discussed, when it comes to deciding which color group to use, first figure out what the output will be. If the output will be on a computer monitor then RGB is the way to go. If the piece will be printed, CMYK is usually the standard and the best option.
Standard 16 Colour Hex Codes :
|Black or 000000||Gray or 808080||Silver or C0C0C0||White or FFFFFF|
|Navy or 000080||Blue or 0000FF||Teal or 008080||Aqua or 00FFFF|
|Purple or 800080||Maroon or 800000||Red or FF0000||Fuschia or FF00FF|
|Green or 008000||Lime or 00FF00||Olive or 808000||Yellow or FFFF00|
Red, Yellow & Blue
These colors cannot be mixed from any other colors. The triangle they form on the color wheel is called the primary triad.
When two primaries are mixed, secondary colors are formed:
- red & yellow = Orange
- red & blue = Violet
- yellow & blue = Green
Orange, violet and green form the secondary triad.
When a primary color is mixed with a secondary color tertiary colors are made:
- yellow & green = Yellow-green
- green & blue = Blue-green
- blue & violet = Blue-violet
- violet & red = Red-violet
- red & orange = Red-orange
- orange & yellow = Yellow-orange
