I'm making wooden planks with the brick texture node and chose 2 grey colours. As far as I understand, it randomly picks a colour inbetween those two. My result contains a cluster of very similar boards, which doesn't look good. I tried making a new brick texture node and using the applying the same settings, but the result doesn't change. Is there a way to randomize the colours again?
It's a bit hacky but you can get new random values by feeding the output of the brick texture into a White Noise texture node.
You can either use a math node to add an offset to the noise to modify the randomness, or set the White noise input to "4D" and tweak the W input, but this is more computationally intensive.
Edit: sorry for the non-colorblind friendly colors.
