JEI's color search does not display the colors of most chisel blocks.

Do you have foamfix installed? If so try Lawful and see if that fixes it.

Forge version?

It doesn't. It still doesn't display the colors even if Chisel, JEI, and CTM are the only mods installed I think.

I would like your full mod please.

Colors aren't displayed when only JEI, Chisel, and CTM installed

I'm using 14.23.3.2689 for the modpack and 14.23.3.2702 for the pack with only Chisel, JEI, and CTM.

why are you using two separate versions?

I haven't updated forge on the modpack yet

Update that first and make sure all your mods are up to date especially JEI.

Only bookshelves and the vent laboratory blocks seem to have colors listed after updating forge and JEI

I can't see why this wouldn't work, seems like a JEI issue. @mezz is there anything that needs to be done specifically to support this feature?

JEI looks at the texture sprites, it seems yours is very weird:

Relevant JEI code here, in debug I see frameCount == 0 so I can't get anything from it.
https://github.com/mezz/JustEnoughItems/blob/677d286ae25772e812f1938a24bac1be2fd7125e/src/main/java/mezz/jei/color/ColorGetter.java#L149-L166

Thanks for looking into it mezz!

So vanilla's lazy copyFrom method doesn't actually copy the texture data...nice. I'll delegate those methods then.
