RGB and RGV

[beamann]

What is the color balance ratio for white light on a RGV system and on a RGB system
RGB RATIO IS:?
RGV RATIO IS:?
I am being told from another forum that C.T laser is wrong for artic white that his ratio is lime green not white and that the only posable ratio is for RGV is 4:1:4

depends on the wavelengths.. also I think 4:1:4 is too weak on violet for an RGV

405 is close to the edge of the visible spectrum so you need tons of power

Which white do you want, D65? For ion at 647,514,488, for example, its 5:1.2:3 for a "standard" D65 white per Lexel's Carol Seidel..

You need to run Tocket's Chroma program, and then try it yourself. Much of how the white is perceived depends on:

1. What it is projected on.
2. Photopic or scotopic vision
3 Source wavelengths
4. Adjacent colors in the image.

Its not a easy issue, as no two of us perceive colors exactly the same. You always need to buy more laser for the red and blue/violet channels then you calculate.

This is my source for that ratio that I told you on the "other forum."

You probably just incorrectly recalled the numbers mister marc gave you, because the RGV ratio of 2:2:1 that you quoted elsewhere will NOT look white, I assure you.
