Generate Brand Color Palettes
Create cohesive color palettes for brand identities, websites, and design systems — from a seed color or a descriptive prompt.
Tool
Choosing brand colors is one of the most consequential design decisions a founder or marketer makes, and most people make it by gut feel, copying a competitor, or picking whatever the logo designer suggested. The result is often a palette that looks fine in isolation but creates problems the moment you need to use it across multiple surfaces — web, print, social, UI.
Color Tools' generate_palette and ai_palette skills generate palettes built for real use — harmonically balanced, with enough tonal range for primary, secondary, and neutral roles, and designed so the colors actually work together rather than just looking good on a swatch sheet.
Founders building brand identities, designers defining design system color tokens, and marketing teams standardizing visual communication across channels use this to move from 'we have a logo color' to 'we have a color system' without paying for a full brand consultant.
