Misturador de cores
Mixing light is not the same as mixing paint, and this mixer shows the difference. Overlap red, green and blue beams and the result gets brighter, ending at white — the opposite of what happens with pigments.
Como usar esta simulação
- Set the intensity of the red, green and blue channels
- Overlap the beams to see the secondary colours
- Read the resulting RGB value
O que observar
- Red and green together give yellow, which surprises most people
- All three at full strength give white, not black
- Turning every channel to zero gives black — the absence of light
A física por trás
Additive mixing applies to light sources: red, green and blue are the primaries because human eyes have three cone types tuned near those wavelengths. Combining all three at full intensity stimulates every cone equally and reads as white. Screens work this way, which is why every pixel is an RGB triple.
