Add transparent color to gradient

Here I’m having an issue againts transparent color
i meant to use like flashing lights on the boarder with Audio Light Visualizations
Maybe adding transparent color is a good idea,
using chroma filter would destroy the whole image


This is actually a bug: you should already be able to. It starts out with the last color transparent. Here is an imperfect workaround: instead of trying to use transparent set alpha/opacity to 1 instead of 0. One tick higher than completely transparent will be hardly noticeable.

oh its true, thanks!
Thinking Alpha 0 would work on transparent

Setting fully transparent (0) fixed for the next version.
