Classes
struct	HSV
struct	HSL
struct	OKLCH

Public Member Functions
HSV	to_hsv () const
	Convert to HSV (h in [0,360), s and v in [0,1]).
HSL	to_hsl () const
	Convert to HSL (h in [0,360), s and l in [0,1]).
OKLCH	to_oklch () const
	Convert to OKLCH (perceptually uniform, CSS Color Level 4) L in [0,1], C in [0,~0.4], h in [0,360).
void	encode (uint8_t *out) const
	Serialize to compact binary (4x float LE, 16 bytes).
Color	interpolate (const Color &other, float t) const
	Interpolate between this color and other by factor t [0,1].
Color	with_hdr_intensity (float multiplier) const
	Scale color intensity for HDR (channels can exceed 1.0).
Color	with_alpha (float alpha) const
	Return copy with different alpha.
uint8_t	r8 () const
	Convert to 8-bit values for serialization/interop.
uint8_t	g8 () const
uint8_t	b8 () const
uint8_t	a8 () const
uint32_t	to_argb32 () const
	Pack to uint32_t ARGB (clamped to [0,255]) for Skia/platform interop.

Static Public Member Functions
static constexpr Color	rgba (float r, float g, float b, float a=1.0f)

static constexpr Color	rgba8 (uint8_t r, uint8_t g, uint8_t b, uint8_t a=255)
	Construct from 8-bit channels [0,255] — convenience for legacy/hex code.
static Color	hex (uint32_t rgb)
	Construct from hex 0xRRGGBB (alpha = 1.0).
