Color picker 5500K is different that CoronaLight 5500K!

Corona Corona for 3ds Max Issues

As in the title:
if we use a CoronaMtl or CoronaLightMtl with 5500K selected with the Color picker we will have a different render than the CoronaLight 5500K numeric value: why?

Hi. Have you tried unchecking the sRGB?

Yes.

probably because self illumination and light emission is a different thing. try it both in coronalight

(*) If I use inside the CoronaLightMtl a CoronaColor map with a numerical 5500K input, everything is ok: Shader and CoronaLight have the same color.

(*) In the CoronaLight: if I use the “Direct input” with 5500K selected with the Color picker and “Kelvin Temp” 5500K input, I have the same problem
In attachment the files.

I think that there is a problem inside the Color Picker slider.

I can confirm:
-5500 in the color picker is 255 229 194 (when I checked it once it was 255 230 194 - wtf?)
-5500 in light or CoronaColor is 255 237 224 (I also got ±1 deviation here for G and B)

Attaching another scene demonstrating this.

Update: I think the problem is rather with the Kelvin temp spinners, since 6500K is slightly blueish there, while it’s perfectly neutral when using the picker.
