RGBA

Copies this color, changing the alpha to the given value

Darken the color by the given amount. This is an absolute amount, not an amount relative to the Color's current lightness. Lightness is clipped at Normalized.MaxValue

Darken the color by the given relative amount. For example, calling aColor.darkenBy(0.1.normalized decreases the lightness by 10% of the current lightness.

Desaturate the color by the given amount. This is an absolute amount, not an amount relative to the Color's current saturation. Saturation is clipped at Normalized.MaxValue

Desaturate the color by the given relative amount. For example, calling aColor.desaturateBy(0.1.normalized decreases the saturation by 10% of the current saturation.

Increase the alpha channel by the given amount.

Increase the alpha channel by the given relative amount.

Decrease the alpha channel by the given amount.

Decrease the alpha channel by the given relative amount.

Copies this color, changing the hue to the given value

Lighten the color by the given amount. This is an absolute amount, not an amount relative to the Color's current lightness. Lightness is clipped at Normalized.MaxValue

Lighten the color by the given relative amount. For example, calling aColor.lightenBy(0.1.normalized increases the lightness by 10% of the current lightness.

Copies this color, changing the lightness to the given value

Saturate the color by the given amount. This is an absolute amount, not an amount relative to the Color's current saturation. Saturation is clipped at Normalized.MaxValue

Saturate the color by the given relative amount. For example, calling aColor.saturateBy(0.1.normalized increases the saturation by 10% of the current saturation.

Copies this color, changing the saturation to the given value

Rotate hue by the given angle

True if this is approximately equal to that
