A solid color system can make a much bigger difference than most people realize. I've found that defining the primary, secondary, and accent colors before designing individual screens keeps the entire UI more consistent.
One workflow that has worked well for me is using a Color Combiner to test multiple color combinations before applying them to buttons, backgrounds, and interactive elements. It helps avoid constant color tweaks later and makes it easier to maintain a cohesive design system across the whole project.
Whether you're designing a website, dashboard, or mobile app, spending a few extra minutes refining your color palette upfront can save a lot of time during development and future updates.
