Frequently Asked Questions
Color temperature refers to whether a color feels warm (reds, oranges, yellows) or cool (blues, greens, purples). It is determined by the hue angle on the color wheel. Warm colors are associated with energy, passion, and coziness, while cool colors feel calm, professional, and serene.
A color's temperature is determined by its hue angle on the HSL color wheel. Reds, oranges, and yellows (0-90 degrees) are warm. Blues, greens, and purples (90-270 degrees) are cool. Saturation also affects perception: low-saturation colors appear more neutral regardless of hue.
Some colors fall into a neutral zone where they are neither distinctly warm nor cool. These include yellow-greens and certain purples. Our tool classifies these as "Neutral" when the temperature score falls within a balanced range, typically influenced by low saturation or a borderline hue angle.
