§Arguments

  • x_value - X axis, either saturation or value (0.0-1.0).
  • y_value - Y axis, either saturation or value (0.0-1.0).
  • color_at - A function that dictates how the mix of saturation and value will be displayed in the 2d slider.

e.g.: |x_value, y_value| HsvaGamma { h: 1.0, s: x_value, v: y_value, a: 1.0 }.into() displays the colors as follows:

  • top-left: white [s: 0.0, v: 1.0]
  • top-right: fully saturated color [s: 1.0, v: 1.0]
  • bottom-right: black [s: 0.0, v: 1.0].
