How to make RGB Gradient light

[tryit32964]

HI

I tried to use the C4d OCTANERENDER to try to make the gradient light in the picture, like the RGB light of the computer fan, but I keep failing, is OCTANE unable to make the gradient color light

Sorry I am using Google to translate, and I can't accurately name the nouns with gradient colors.

I hope it can help me, I can't find similar teaching on the Internet, or my keyword is wrong
