NCS color to radiance material

oh wow, thank you for your reply!

this is a cool tool!

but my question why in color picker ( by default y=2.2) when I change y=1.0 the reflectance, respectively the radiance material is always the same?

and can i have reflectance from EASYRGB? is there a way to check reflectance of color?

Thank you !
