Color mixer that can mix 3 or more colors?


Question

I'm looking for some sort of service, tool or application – even manual techniques – where you can digitally mix/blend 3 or more colors (i.e. not 2 as in most applications out there) and get the results in HEX/RGB/CMYK/CIELAB, etc.

Immensely thankful for any tips!

Question background (no necessary read)

One of the main reasons I'm looking for an accurate way of doing this, is for the application of sampling colors from an image when building e.g. color identities. Most color sampling tools tend to be pixel precise, so in order to get the right color (among various nearby candiate pixels), you need to have a lot of patience. Even then, the exact color you're after may not be there – yet it's there, so to speak. (Yep, I know it might be superficial.) Anyway, what I use to do in those situations, is to sample one color that is close to what I want, and another close ditto, then mix them both and settle for the middle (superficially 'correct') color. My problem is that I often wish I could mix a bunch of colors (≥3), to get more accurate blends, finding that perfect blend in-between.

That's one situation where I have a need for this, but there's another case (probably even more important): At some point I begin to arrive on a final scheme (during which I might have some 10 colors remaining, which still needs to be reduced to about 2–4 colors). In this situation I often find it a useful method to consolidate, or abstract multiple (similar) colors into single ones (especially if they originate from the same source of element, or if they appear as shades of the same color). Again, it would be great if I could just throw 'em in a 'blender' and move on.

Accepted Answer

I have finally found a tool that does the job:

An online service called Colorhexa.

Using this tool you may enter e.g. #00ACE6 + #FFEE4C + #EA0085 + #CE1BBD and it politely hands you the resulting blend, #ae6d9d!

You may omit the hashes (#) and you can even blend different color formats such as any combination of RGB, CMYK, HSL, HEX, etc. in one go!

Maybe this is kludgy, but you could use an image-editing application like GIMP or Photoshop to place each color in a layer, mix them, flatten, then sample the color.

I think the problem you are going to have is that mixing colors is more than just colors on top of each other. It is also a matter of transparency and specific blending modes. Mixing too many colors could quickly end up with either white (RGB, additive) or muddy (CMYK, subtractive).
