An equal amount of red and blue make magenta actually. see: RGB.

Red, Green and Blue are the additive primary colors, while Cyan, Magenta and Yellow are the subtractive primary colors in the RGB colorspace (0,255,255) is yellow. Green isn't (0, 255, 128), that's a color halfway between green and cyan. Green is (0,255,0).

let's help: (0, 255, 0) means:

  • Red: 0
  • Green: 255
  • Blue: 0

scaled to percentages:

  • Red: 0%
  • Green: 100%
  • Blue: 0%

Gosh I wonder what color you get ? ;-)

Red and Green make Yellow because: The monitor transmits equal amounts of red and green light. Your eyes pick this up, your eyes have 3 different kinds of cone cells, (roughly 1 that has a peak response at red, one at green, and one at blue) in reality it's a bit more complex, but for now that'll do.

Now the *idea* is that if you have a monochromatic yellow light source, your red and green cones both respond. The monitor fools your eyes into thinking they're seeing yellow by putting out a separate red and green light tuned exactly the right wavelength for those receptors

Sometimes I wonder what a space alien would see if (s)he ever looked at one of our earth monitors, since the trick only works for earth vertebrates (and specifically humans.)

Anyway, you're finding your r,g, and b values quite oddly. How about grabbing photoshop or gimp and actually plugging some values into the built in color selector in those packages? That will dynamically cross-calculate values for you.

or you can grab some of the source from Hex_triplet and experiment in your own sandbox

I've added some values to your sandbox already, hope it gives an idea? Kim Bruning 20:10, 3 Apr 2004 (UTC)
