Public Member Functions
constexpr	Color (float r, float g, float b, float a=1.0f) noexcept
	Constructs a Color from individual float components (0.0f to 1.0f).
constexpr	Color (uint32_t i, Type type=Type::RGB) noexcept
	Constructs a Color from a packed 32-bit integer. The 'type' parameter defines the component order.
	Color (std::string hex, float a=1.0f)
	Constructs a Color from a hexadecimal string (e.g. "#FF00FF").
constexpr Color	Lerp (const Color &other, float t) const noexcept
	Returns a color that is the linear interpolation between this and another color.
Color	Normalize () const
	Normalizes this color (treating it as a 4D vector).
constexpr float	Length2 () const noexcept
	Returns the squared length of the color vector.
float	Length () const noexcept
	Returns the length of the color vector.
constexpr uint32_t	GetInt (Type type=Type::RGBA) const noexcept
	Returns the packed 32-bit integer representation.
std::string	GetHex () const
	Returns the hexadecimal string representation (e.g. "#FF00FF").
