不是那種會疊加的刷子 NOT a brush that overlays
基本上就是模擬你把 一個設定為疊 加的彩色圖層 放在線條上時的 效果,因為主色是線條,子色是顏色。
混合模式設為線性燒錄,因為我大多用在黑色上,但如果你打算用在較淺的顏色上,我建議改成乘法或其他方式。

我 完全不知道還有誰會用這個
It's basically simulating the effect you get when you put a colored layer set to overlay on top of your linework, as the main color being the linework and the sub color as the color.
Blending mode is set to linear burn because I mostly use this with black but if you're planing on using it with lighter colors I reccomend changing it to multiply or something else.

I have no idea who else would use this
