Colors take a big part in the creation of an illustration and selecting the right color palette for your design is something which is certainly worth taking some time to think about.
I mostly stick to my main color palette which I created and updated over time because I like to find continuity in my work. I use bright colors simply because I usually feel more satisfied working with these kinds of tones. I like my designs to pop out and inspire happy feelings so it's a good way to go.
But when I want to work with something a bit different and refreshing (whatever the reason is: a client request or the will to get out of my comfort zone and explore a bit) I don't just pick random colors and see where I can go from there. I carefully look for new ideas and inspiration on different platforms.
There are so many resources you can find online so I decided to select a few of my favorites in this post to hopefully guide you to some tools that you’ll find are easy to use and super efficients for your designs!
I mostly use Pinterest at the very beginning of my research process, when I really have no idea where to go and when I just want to look around and see which kind of picture attract my eyes and inspires me. So I'd suggest to simply type in "color palette" in the research tool bar and keep scrolling. I never use a color palette I found straight from Pinterest but it drives me to the kind of color scheme I want and it's a good start to help me go further into my research.
I think this one is my favorite so far and the one I use the most. Adobe Color let you create color schemes from a first color you choose, following different color rules: monochromatic, triad, complementary, compound, etc. You can also explore thousand of color palettes created by the Adobe community (simply type in key words of the kind of palette you are looking for). You can save your favorite choices in your library to use later or compare ideas!
Looking for contrast? Hello Color is generating endless contrast colors and is super simple to use. Chose the first color or generate a random choice and let the magic happen!
This one will help you find a more uniform palette. You can generate a random one or adjust your own and then modify the intensity to create different versions of it, all from the same base.
This last one here allows you to find beautiful photos and the color palettes generated next to them. It gives you a better sense of the color scheme of a picture and it definitely helps find easy inspiration for your design.
So here was my short selection, but the list can go on and on!
Too many options can be confusing though, so sticking with a few of your favorites is definitely a good start to help you get inspired.
