Wouldn't magenta just be red mixed with white? That's how you do it with paint.

- pavlov 13y agoPaints and light mix differently. One is subtractive, the other additive. With paint, you start with white (full reflectivity) and add pigment to block out reflected light. With light, you start with black (darkness) and add photons of different wavelengths. When you have an even mix of all wavelengths, you have white light.
- dietrichepp 13y agoNo. You'd have to mix in some blue, and then you'd just end up with a muddy purple. You can prove it to yourself by looking at any painting from before about 1860. See any magenta? No. Magenta pigment was not available until 1859, and it could not be mixed from other colors without getting a muddy result. Edit: Here's an example: http://en.wikipedia.org/wiki/File:Bouguereau-Psyche.jpg http://en.wikipedia.org/wiki/File:Bouguereau-Psyche.jpg The painting (Psyche by Bouguereau) was done in 1890 and could not have been made thirty years earlier.
