I use Contrast paints a lot. It took some trial and error to understand how to use them effectively but now they are the primary tool in my painting projects. The only problem is that I enjoy using them so much that I am constantly planning new projects instead of finishing what I have started. Contrast paints haven't helped me to finish models but I reach the point of giving up faster and more often so I guess that is still an improvement
Imagine traditional basecoat-shade-highlight process without having to paint the basecoat at all. That's how much Contrast paints save time.
You won't find many finished models from my Instagram but everything there is painted using mostly Contrast paints.
