Make an object monochromatic to match a color (not B&W)

[hellobill]

Hi,

I'm using Affinity Designer on Windows. I want to make some objects monochromatic to match a specific color.

I know I can do Layer > New Adjustment > Black & White, and then Mask to Below to make it greyscale. And I can use other layer options to mess with teh colors/look. But what if I want the monochrome scale to be specifically/exactly RGB hex value 90298D?

I'm sure there's an easy way to do this, but I've been beating my head against the wall on it. Any help appreciated.

Cheers,

Hi @hellobill

I would use a Gradient Map Adjustment layer for this, there is no need to convert to B&W. Add the Gradient Map adjustment Layer, It will come up looking a bit odd as it uses red blue & green  by default. Just click the colour selector, change the options for colour to RGB Hex sliders, type your code into the Hex Box, then select your next point on the gradient, switch the colour select mode to HSL Sliders, adjust the lightness slider to get the tones you need.
