Rainbow effect in C#

Hi. Does anyone has code on a rainbow effect in C # ? I searched the forum but have not found and completely I don’t know how to do it,

We need a little more context. Where do you want this rainbow effect to appear? On the screen? In a texture? In a skybox?

In a slider.

Isn’t a rainbow just a colored texture that is transparent? Draw the texture, put it on a sprite, make it the size you want, put it in the scene and you’re done.

I imagine a rainbow would be handled much like a “god ray,” which is basically a type of simulation of a volume lighting phenomenon associated with atmospheric scatter.
