Color Input
A Gio library for color input widgets
TODO
- The tone of a color is not what is shown under the control of the picker
- Maybe we need to use the HSL colorspace instead of HSV
- Maybe the gradient can be drawn differently
- Make the control of the tone and hue picker align to the middle of a mouse event
- Fix issue with size of hue slider when the width in pixels is not a multiple of 6

type HSVColor ¶
type HSVColor struct {
// H stands for hue and is the rgb portion of the model,
// expressed as a number from 0 to 360 degrees:
// Red falls between 0 and 60 degrees.
// Yellow falls between 61 and 120 degrees.
// Green falls between 121 and 180 degrees.
// Cyan falls between 181 and 240 degrees.
// Blue falls between 241 and 300 degrees.
// Magenta falls between 301 and 360 degrees.
H float32
// S stands for saturation and describes the amount of gray in a particular rgb,from 0 to 1.
// Reducing this component toward zero introduces more gray and produces a faded effect.
S float32
// V stands for value and works in conjunction with saturation and describes the brightness or intensity of the rgb,
// from 0 to 1, where 0 is completely black, and 1 is the brightest and reveals the most rgb.
V float32
}
HSV is a cylindrical rgb model that remaps the RGB primary colors into dimensions that are easier for humans to understand.
