# Objective Closes #10319 ## Changelog * Added a new `Color::rgba_from_array([f32; 4]) -> Color` method. * Added a new `Color::rgb_from_array([f32; 3]) -> Color` method. * Added a new `Color::rgba_linear_from_array([f32; 4]) -> Color` method. * Added a new `Color::rgb_linear_from_array([f32; 3]) -> Color` method. * Added a new `Color::hsla_from_array([f32; 4]) -> Color` method. * Added a new `Color::hsl_from_array([f32; 3]) -> Color` method. * Added a new `Color::lcha_from_array([f32; 4]) -> Color` method. * Added a new `Color::lch_from_array([f32; 3]) -> Color` method. * Added a new `Color::rgba_to_vec4(&self) -> Vec4` method. * Added a new `Color::rgba_to_array(&self) -> [f32; 4]` method. * Added a new `Color::rgb_to_vec3(&self) -> Vec3` method. * Added a new `Color::rgb_to_array(&self) -> [f32; 3]` method. * Added a new `Color::rgba_linear_to_vec4(&self) -> Vec4` method. * Added a new `Color::rgba_linear_to_array(&self) -> [f32; 4]` method. * Added a new `Color::rgb_linear_to_vec3(&self) -> Vec3` method. * Added a new `Color::rgb_linear_to_array(&self) -> [f32; 3]` method. * Added a new `Color::hsla_to_vec4(&self) -> Vec4` method. * Added a new `Color::hsla_to_array(&self) -> [f32; 4]` method. * Added a new `Color::hsl_to_vec3(&self) -> Vec3` method. * Added a new `Color::hsl_to_array(&self) -> [f32; 3]` method. * Added a new `Color::lcha_to_vec4(&self) -> Vec4` method. * Added a new `Color::lcha_to_array(&self) -> [f32; 4]` method. * Added a new `Color::lch_to_vec3(&self) -> Vec3` method. * Added a new `Color::lch_to_array(&self) -> [f32; 3]` method. ## Migration Guide `Color::from(Vec4)` is now `Color::rgba_from_array(impl Into<[f32; 4]>)` `Vec4::from(Color)` is now `Color::rgba_to_vec4(&self)` Before: ```rust let color_vec4 = Vec4::new(0.5, 0.5, 0.5); let color_from_vec4 = Color::from(color_vec4); let color_array = [0.5, 0.5, 0.5]; let color_from_array = Color::from(color_array); ``` After: ```rust let color_vec4 = Vec4::new(0.5, 0.5, 0.5); let color_from_vec4 = Color::rgba_from_array(color_vec4); let color_array = [0.5, 0.5, 0.5]; let color_from_array = Color::rgba_from_array(color_array); ```
