PaletteRx Step 2 (Color Balance) provides four metrics that evaluate different dimensions of your palette's composition.
Temperature Balance
Measures the distribution of warm colors (reds, oranges, yellows) vs. cool colors (blues, greens, purples). A score near 50% means equal representation. Neither extreme is wrong. It depends on your brand. But awareness prevents accidentally skewing your palette.
Vibrance
Measures the average saturation across your chromatic colors (excluding bases). High vibrance means bold, energetic colors. Low vibrance means muted, sophisticated tones. If you intended bold colors and your vibrance is low, some of your "colorful" colors might be more muted than you realize.
Lightness Distribution
Evaluates how well your palette covers the lightness spectrum from very light to very dark. A palette clustered in the mid-range will struggle to create visual hierarchy.
Diversity
Measures how many distinct hue families your palette covers. Higher diversity creates more visual interest but requires more skill to harmonize. Lower diversity is easier to manage but can feel monotonous.
Using the Metrics
These are not pass/fail scores. They are descriptive tools. A fashion brand palette might intentionally score low on diversity (monochromatic scheme) and high on vibrance. A corporate palette might score high on diversity and moderate on vibrance. The metrics help you confirm that your palette matches your intention.
