We have already shared some thoughts on every of preps from the above. However, I have found providing you with a single source of color palettes insufficient, so here come more which we use and recommend you to.
And yeah, I am sure you are brilliant at combining and matching colors as well as finding the most extraordinary and winning solutions. But, you know, a pinch of extra tips has never been too much 😉
Adobe Color CC
Adobe Color allows creating and sharing palettes of 5 colors, so the simples it to check out what other users have already made up. You can edit them to your demands and save for later design work. It is pretty rejoicing that the library of the user-created content is so rich and varied, so you are likely to find the exact match.
Alternatively, you can create a custom palette: either manually (which is more complicated and requires some knowledge of color theory and a good eye) or by importing and experimenting with an image of yours.
Moreover, the built-in color palettes of Dribbble are so handy and easy to use! All you need is to find a reference you like and download the color palette featured below.
Or you can pick a color you particularly like and find all images (and palettes) featuring it. I usually end up with tons of fascinating solutions with I export in .aco format and test in Photoshop for my project. Sounds very simple (and it really is), but the color search should be like that, no?
Of course, you can return to Adobe Color for that, but to me, the color palette generator by Canva feels more fluent and usable, and you can simply keep it in your bookmarks for the case.
