Replace Colors?

[JunmaKun]

I  tried to replace the faded color in a photo to a brighter red but though I had the "replace color" brush selected it painted bright red over the image. I looked it up in the tutorial and the tutorial showed exactly what I wanted to do but though I had the correct brush selected it didn't do it. I closed the program, picked another photo and chose green to brighten the field, and it toned it a light pink, chose red, it turned dark. I am using a trial copy of Afinity Photo - does that mean that some brushes automatically do not work? Admittedly I'm accustomed to Adobe Photoshop where one merely chooses the "replace hue" brush and it does just that. Not sure what to do?

Hi JunmaKun and Welcome to the Forums,

The Trial version is the full app, so the brushes and other tools will work.  When using the Colour Replacement Brush Tool in Affinity Photo, you first need to select the colour you wish to change to on the Colour Panel. I'd stick with one of the Basic brushes, you'll have options to adjust on the Context Toolbar like Width, Opacity etc, you can also adjust the Tolerance level. Remember this process will replace the targeted colours hue with the replacement colours hue while retaining lightness.

Which is why I think the brush is very poorly named -- if it was named "Hue Replacement Brush" it would be much more obvious what it does & avoid a lot of unnecessary user confusion!

"Hue Replacement Brush"

Does it mean, there are 3 replacement brushes: a Hue, a Saturation and a Lightness brush?

Or is it rather 1 replacement brush – with options to tick on/off – for H | S | L?
Or one for Hue only, with sliders for density of S and L?

Where do you see any sliders or any other options for the brush, other than for the usual Color, Width, Opacity, Flow, & Hardness like for any other brush tool, plus a tolerance option?
