If blending is at 0%, persistence fails to have any real effect.

I turned off all pressure sensitivity (actually I just used my mouse) to emphasize the effects in a controlled environment: So for this example I’ve done the same test with three different levels of blending. Basically, the higher the persistence, the longer it will take for the color to shift as you make a stroke, and subsequently, from which color to which other color it is shifting is dependent on the blending setting. Like blending, Persistence is only really relevant when painting over existing color so it’s mostly unaffected by transparent pixels. Rather, how long it “persists” if you will. Basically, it controls how easily a brush shifts color as you are blending from one color to another. This one goes hand-in-hand with blending. Keep this in mind - if you ever can’t paint for some reason, check your dilution setting, it might have gotten accidentally bumped to 100! In fact, if you were to switch to binary color mode and look at this layer, there would literally be nothing there anymore! So in this example, you can see that as dilution approaches 100%, the color I’m painting with basically becomes invisible. Dilution can be thought of as the inverse of the Blending setting in some ways. So it won’t do anything if the whole layer is already filled in (even with white). Dilution is ONLY affected by transparent pixels. A 0% Dilution will result in the brush painting very easily onto a blank surface, while a brush with 100% dilution will literally not paint on blank parts of the layer at all. This controls how readily the brush will draw on a blank (transparent) part of the layer. So you can see from this example that the color I’m using gets harder to paint as the blending increases and more of the existing green is absorbed, until at 100% it is just completely turning green. Blending is not affected by transparent pixels, so if you’re drawing on a blank layer it will have no effect. So at 100%, the color you’re using won’t even show up, unless you move to a transparent area. A 100% blending setting will ONLY pick up existing colors (provided there are any). For example, a 0% blending setting will pick up no existing colors, treating it as if you were painting on a transparent layer.

This controls how readily the brush will inherit any colors you are painting over with it.

Painttool sai 1.1.0 update#
I don’t claim to be an expert so if you find I’ve made a mistake, let me know so I can update it, thanks! :3 I know there are multiple translations of SAI floating around, so if some of these terms don’t sound familiar, just know that I’m talking about the three settings that appear under the texture in the brush tool settings (note that this won’t apply to any tool types except for brushesand watercolor brushes). I decided to sit down and figure it out, and I have thrown together a short reference guide for anyone who is confused about them. I’ve had a general idea what these things did but wasn’t completely sure what their specific functions were.
