Color

1. Never Use Slider Control or Angle Control to Change Colors

Sometimes you may want to allow the user to change only the hue, saturation or brightness of a color and not all three at once.

When this is the case, you should still use a Color Control since it’s more intuitive for users to pick from a color picker, rather than a

Slider⁠

Angle⁠

You can use expressions to modify the hue, saturation or brightness, as shown in the code example below.

Alternatively, you can use the Hue Color script from

Author Tools⁠

VC Color Vibrance⁠

// Convert RGB to HSL

let hsl = rgbToHsl(inputColor);

// Example: Set HUE to 30 degrees

hsl[0] = 30;

// Example: Lower saturation for 50%

hsl[1] *= 0.5;

// Example: Increase brightness for 100%

hsl[2] *= 2;

// Convert back to RGB

let rgb = hslToRgb(hsl);
