Sometimes we make mistakes (often if you’re me!) and instead of starting again we need to go through a process of error correction.
To do this the best process is to get the color of the original mistake, dust it on top over the affected area to reduce it’s contrast, then if that mistake wasn’t in white, to dust over the contrast reduced area with straight white paint.
Make sure that the coverage of the white completely hides the mistake.
Your next step is to mix a concoction of transparent colors that match that original color and begin applying the paint from the inside out. It’s important to build it up extremely slowly in layers so as not to go too dark.
