Building Your Color Palette
I made a tool a little while ago that helps generate color shades and blends: <a href="https://colorkit.io" rel="nofollow">https://colorkit.io</a>
It's nice that Bootstrap, Tailwind, and other libraries come with default shades of gray and colors, but I think these should typically be customized to match the brand, so I made this tool to speed up that process!
