Deck Color Visualizer

The deck color visualizer analyzes a base color and generates harmonized palettes suitable for slide decks used in presentations, marketing, and product briefings. It targets designers, brand teams, and decision makers who need fast, repeatable color schemes that align with a defined mood and branding.
Conceptually, the tool converts input colors between hex and perceptual spaces (HSL) and applies color harmony models (analogous, complementary, triadic, tetradic, and monochromatic) to produce a list of hex values. It optionally adjusts saturation and lightness to balance vibrancy with readability on screens.
Core features include deterministic palette generation from a single base color, control over palette size, built-in accessibility checks against WCAG contrast targets, and export options for CSS variables, swatches, and slide-ready assets. It supports rapid iteration when refining a deck’s visual identity.
Unique value comes from theory-based generation combined with practical export formats and real-time consistency across slides. The tool avoids branding surprises by offering neutral defaults and clear documentation for designers and engineers integrating the palette into slide templates.
