Can't figure out how to merge COLORS in any of the Affinity (Photo, Designer, Publisher)

[LSDJE]

I can't figure out how to merge, let's say 2 colors - like yellow and blue - which would be a green of some kind. (that is just an example of colors)

I have a variety of specific colors - that I would know what it would turn out to be if I combined them - also, let's say it was 50% of one and 50% of the other color.

I tried changing the transparency of the layers - but don't think that is really correct - doesn't look like what I intended ?

As always - thank you all!

Hi, 

could you explain for what purpose you want to mix colors?

you may start using cmyk document format, as this better matches subtractive color mixing.

It makes a great difference if you need to mix e.g. a fill color for a large area, or use a brush and want to mix different shades instead of exactly two colors e.g. for water painting / aquarelle effects.

There is no direct function in software like Affinity to realistically simulate the mixture of two colors extracted from a tube on a palette/mixing tablet in real life.

Affinity supports layer blending - but this more or less strictly adheres to „industry standard“ rules, using partial transparency. This process is more physical / mathematical and does not match real color mixture.

There is a mixing brush to simulate the real process, but probably you are looking for something different.

I believe you can merge swatches for a "new color" in Adobe Illustrator - that's what I want to do. SO, I will be mixing stains actually - and before I start to physically mix a million trials, I wanted to at least give it a whirl on scrreen to see if it matches my goal color. I know the RGB values of the colors I would be mixing - and used that for the 2 square shapes. I also know the ending RGB value I want to get to - but can't figure out how to get to the final by mixing the fixed values I can not change.

Being able to do this would be helpful for many print design features as well.

Does this info help?

Unfortunately this isn't possible in Affinity currently, my apologies.

I don't wish to sound obvious, but is there a reason you cannot simply create a 'final' swatch using the desired colour values that you have?

Although not possible directly in Affinity, there are many online resources for colour mixing using specific values that may help you to find the desired RGB values

[LSDJE]

I have 4 to 5 RGB colors, that I can not change - and want to find a ratio mix (1:2, 1:3, 1:4, etc) closest to the final RGB value.

I just thought I could do it in Affinity - I'll figure out another way - but Affinity was  my first go to for this since Illustrator does have a swatch merge, I thought possibly Affinity may have something similar that I had not yet found.

Thank you!
