PaletteRx's Health Score is a 0 to 100 metric that measures how complete, balanced, and production-ready your palette is. It is not a subjective quality rating. It is an objective checklist of five structural requirements. Each checkpoint contributes 20 points.
Checkpoint 1: Color Count (20 points)
Does your palette have enough colors to be functional? A single color cannot be a system. PaletteRx expects at least 4 colors for a minimum viable palette. Fewer than 4 fails this checkpoint. The sweet spot is 6 to 10 colors. More than 12 starts to introduce complexity without proportional benefit.
Checkpoint 2: Base Colors Present (20 points)
Does your palette include both a light base and a dark base? These are the foundational neutral colors that every production palette needs. If either is missing, this checkpoint fails. PaletteRx identifies bases by analyzing lightness: very light colors (L > 90%) and very dark colors (L < 15%) qualify.
Checkpoint 3: WCAG Compliance (20 points)
Does every chromatic color have at least one accessible pairing? A color that fails WCAG against every other color in the palette is unusable for text or interactive elements. PaletteRx tests all pairs and checks that each color has at least one AA-passing partner.
Checkpoint 4: Color Balance (20 points)
Is the palette reasonably balanced in terms of temperature (warm/cool mix), vibrance (saturation distribution), and hue diversity (not all the same hue)? Extreme imbalance in any dimension costs points. This is the most nuanced checkpoint and the one most influenced by artistic intent.
Checkpoint 5: Role Coverage (20 points)
Are the essential roles assigned? PaletteRx expects at least Primary, Light Base, and Dark Base roles to be filled. Missing essential roles means the palette is not ready for export because the export templates need these roles to generate correct output.
