Are there any tools for creating a color scheme based on two specific colors (or resources that explain the technique/intuition behind it), since the only ones I have found are based around creating a color scheme from one base color.
You can use coolors.co which is an awesome site, where you can generate awesome color palettes.
there is this cool feature where in you can start with two colors then lock both of them and generate color scheme until you feel that color scheme works for you.
and there are many other sites but this one just works for me. hope this helps :)
