hi ^_^

1) flatten original drawing to a single layer

2) make a layer behind the og drawing layer and fill it with a solid, fully saturated, medium-light color (ex. pink or orange)

3) adjust the opacity of the original drawing layer (in the middle, sandwiched btwn the HUE layer and solid bg color layer) to your liking~ (below: 60%, 32%, 0%)

AND YOU'RE DONE!! YAY ✨

Note: the bg color underneath can be any hue, and the exact value doesn't matter either (i would go for medium-light for pastel look- not dark or very light) but it must be saturated! If it is not saturated, then the hues from the "hue layer" won't be transferred! If it is completely grey, the hue layer won't work at all:

Note 2: this effect is not the same as just lowering the contrast! I tried lowering the contrast using CSP's function and it gave me this ugly grey result (it's the same as if the "bg color" was set to grey, like the above pic!) So this "hue filter" method lowers the contrast while keeping rich, dreamy colors!!👀✨
