So when Im thinning or mixing paint, im doing it with an eyedropper in attempt to keep track of ratios. this seems inefficient and inaccurate, and i think its going to become an issue when i need a custom color duplicated, requiring specific ratios. in fact, its almost an issue now because i (think i) need to mix a custom color to drybrush with. (ex: ) i see someone saying, "mix 1 to 15 to achieve X". to me, that's either 16 eyedroppers or 16 individual drops. measuring by the drop is the frustrating part. is there a tutorial, or can anyone share what tools/methods they use to achieve said ratios so accurately? is this one of those things i just need to be more patient with and master, or is there a better way to do it? thanks in advance oh, i use an airbrush if that's not implied.
