Question regarding the color replacement brush

[zBernie]

I'm trying to paint the swan below a turquoise color.  I originally used the recolor adjustment, which looks pretty good.  But I thought since the color replacement brush maintains shadows and highlights, it would look better.  Using the color replacement brush, I can only obtain a slight color change as shown on the birds wing on the right.  I'm guessing that the brush is not a good choice for light objects like this swan?

The colour replacement brush acts more like a hue replacement brush, you can test this out by creating a new fill layer changing it to the colour you want and then changing the blend mode to hue, you will notice the bill will change to a strong colour and any part of the swan that has some RGB value will get more colouring, but pure white will be left untouched.

You could select the area you want to modify, apply a Channel Mixer adjustment, and then adjust the colour values and blend mode to taste

Here I dialled down the red value in the red channel from 100% to 41%, and set the blend mode to Multiply.

Before:

After:

The orange bill is masked out and not affected by the adjustment. Play with the values in the other channels to modify the colouring.

(BTW I'm pretty sure that's a swan, not a goose 😆)

You could even say it is a hue replacement brush

From the Help:

The targeted color's hue will be replaced with the current Primary color's hue, while retaining saturation and lightness values of the original pixels.

Thanks you that works very well!  And also maintains the highlights and shadows.  And I meant to says swan, not goose!  :)

Making it the worst named tool in all of the Affinity apps.

Hm. "vector brush" is a strong competitor, isn't it?

I think that has to take second place behind the Color Replacement Brush because there are a couple of for-real vector brushes, even though they are trivial ones.
