thank you!! it's a mix of experimenting (using some color theory ive learned over the years) and various color-picker sites! I don't have one I remember off the top of my head, but i recently learned duckduckgo will offer color combos if you search for 'css (colorname)' :)
for e.g., i like soft muted analogous colors paired with a bright complementary accent color. using just that you can do a lot of variety!
thank you! always been a muted colors kinda guy ^_^
