Frequently asked
Color converter questions
When should I use HSL instead of HEX or RGB?
HSL separates hue, saturation, and lightness into independent values, making it easier to create a consistent color palette by adjusting lightness alone, without recalculating an entirely new hex code.
Does this support alpha transparency?
Yes, HEX with an 8-digit alpha channel, rgba(), and hsla() values are all converted so you can carry transparency across formats consistently.
Why do two tools show slightly different RGB values for the same color?
This usually comes down to rounding differences when converting between color spaces, or a difference in color profile handling between the browser and a design tool like Figma or Photoshop.
