Help I am having a problem with colours, when I paint them they are affected by the colours they are painting over, this only happens when working over colours on the same layer.
I have set the brush to presets, doesnt change anything. when painting on white it even effects it. it wasn't always like this, i don't know what happened. I hope somebody can help and thank you.
You have the brush mode set to Pin Light in the Options bar
thank you. solved the problem, clearly there are a few gaps in my photoshop knowledge.
