Rainbows gone, color too

[Mystery Keeper]

I used this code on video
separatefields()
a=selecteven().DeRainbow(10)
b=selectodd().DeRainbow(10)
interleave(a,b)
weave()
And here's what I've got.

As you see, the black belt became redish. 'Tis not the result of following code, but certainly of DeRainbow. How can I get rid of rainbows but evade this color corruption?

Thanks. Though it doesn't help much.
Bifrost keeps the colors, but doesn't remove rainbows just as good. Guess I'll stick to it anyway.

Have you tried checkmate?

[Mystery Keeper]

Yes, I have. Been the most ineffective.

Hmm...martino posted something a while back that might help.
