depends on what ?

yellow is overbright orange? that's how rgb color works.

so , what about this white color sir : if it will be random , so why i am choosing blue or any different color

emission range 0-5

emission range 0-10

emission range 0-10 (points changed)

what is the common way to avoid color which we dont want ?
what emission color range should be as a number ?
Is there a common numbers or it is up to us ?

Thanks !!

It's not random. That's just how overbright colors work with a naive (clamping) LUT. If you want filmic behavior for overbright values you'll need a filmic tonemap to map values onto the screen.

For example, with a generic gamma curve viewing space, an emission color of (0, 0.1, 1) will produce a color of (0, 1, 1) on the screen if the emission brightness is 10. The reason you see yellow or white is the same.

Not seeing any red when you change the emission range is for a different reason and has nothing to do with digital color theory. The ramp is mapped to a range that exceeds the input values of the emission field, ie the end of the ramp is unused. A lesser emission range maps more of the ramp to input values.

oh thanks really i understood well , sorry for delay message
