Color.HSV

static Color HSV(float hue, float saturation, float value, float opacity)

   
float hue Hue most directly relates to the color as we think of it! 0 is red, 0.1667 is yellow, 0.3333 is green, 0.5 is cyan, 0.6667 is blue, 0.8333 is magenta, and 1 is red again!
float saturation The vibrancy of the color, where 0 is straight up a shade of gray, and 1 is ‘poke you in the eye colorful’.
float value The brightness of the color! 0 is always black.
float opacity Also known as alpha! This is does not affect the rgb components of the resulting color, it’ll just get slotted into the colors opacity value.
RETURNS: Color An RGB color!

Creates a Red/Green/Blue color from Hue/Saturation/Value information.

static Color HSV(Vec3 hsvColor, float opacity)

   
Vec3 hsvColor For convenience, XYZ is HSV. Hue most directly relates to the color as we think of it! 0 is red, 0.1667 is yellow, 0.3333 is green, 0.5 is cyan, 0.6667 is blue, 0.8333 is magenta, and 1 is red again! Saturation is the vibrancy of the color, where 0 is straight up a shade of gray, and 1 is ‘poke you in the eye colorful’. Value is the brightness of the color! 0 is always black.
float opacity Also known as alpha! This is does not affect the rgb components of the resulting color, it’ll just get slotted into the colors opacity value.
RETURNS: Color An RGB color!

Creates a Red/Green/Blue color from Hue/Saturation/Value information.

Examples

// You can create a color using Red, Green, Blue, Alpha values,
// but it's often a great recipe for making a bad color.
Color color = new Color(1,0,0,1); // Red

// Hue, Saturation, Value, Alpha is a more natural way of picking
// colors. The commentdocs have a list of important values for Hue,
// to make it a little easier to pick the hue you want.
color = Color.HSV(0, 1, 1, 1); // Red

// And there's a few static colors available if you need 'em.
color = Color.White;

// You can also implicitly convert Color to a Color32!
Color32 color32 = color;
// Desaturating a color can be done quite nicely with the HSV
// functions
Color red = new Color(1,0,0,1);
Vec3 colorHSV = red.ToHSV();
colorHSV.y *= 0.5f; // Drop saturation by half
Color desaturatedRed = Color.HSV(colorHSV, red.a);

// LAB color space is excellent for modifying perceived 
// brightness, or 'Lightness' of a color.
Color green = new Color(0,1,0,1);
Vec3 colorLAB = green.ToLAB();
colorLAB.x *= 0.5f; // Drop lightness by half
Color darkGreen = Color.LAB(colorLAB, green.a);
