[1.6.4] Items in inventory appear dark

[andreidim]

Hello everyone.

While working on my mod I noticed that certain blocks appear darker in the inventory.

When I place some things on the hotbar, the stack of items appears to have a dark color.

When I place something in the rest of my inventory it's the right color, but, when I pick the stack up it darkens again.

 

How could I fix the problem, I'm worried that it will break other mods and stuff

The problem is that I'm not using an ISimpleBlockRenderingHandler, how could I fix it? It seems like it's happening when I have my custom block in my inventory and I'm not using a tesselator
