# Objective
- Fixes#12068
## Solution
- Split `bevy_render::color::colorspace` across the various space
implementations in `bevy_color` as appropriate.
- Moved `From` implementations involving
`bevy_render::color::LegacyColor` into `bevy_render::color`
## Migration Guide
###
`bevy_render::color::colorspace::SrgbColorSpace::<f32>::linear_to_nonlinear_srgb`
Use `bevy_color::color::gamma_function_inverse`
###
`bevy_render::color::colorspace::SrgbColorSpace::<f32>::nonlinear_to_linear_srgb`
Use `bevy_color::color::gamma_function`
###
`bevy_render::color::colorspace::SrgbColorSpace::<u8>::linear_to_nonlinear_srgb`
Modify the `u8` value to instead be an `f32` (`|x| x as f32 / 255.`),
use `bevy_color::color::gamma_function_inverse`, and back again.
###
`bevy_render::color::colorspace::SrgbColorSpace::<u8>::nonlinear_to_linear_srgb`
Modify the `u8` value to instead be an `f32` (`|x| x as f32 / 255.`),
use `bevy_color::color::gamma_function`, and back again.
###
`bevy_render::color::colorspace::HslRepresentation::hsl_to_nonlinear_srgb`
Use `Hsla`'s implementation of `Into<Srgba>`
###
`bevy_render::color::colorspace::HslRepresentation::nonlinear_srgb_to_hsl`
Use `Srgba`'s implementation of `Into<Hsla>`
###
`bevy_render::color::colorspace::LchRepresentation::lch_to_nonlinear_srgb`
Use `Lcha`'s implementation of `Into<Srgba>`
###
`bevy_render::color::colorspace::LchRepresentation::nonlinear_srgb_to_lch`
Use `Srgba`'s implementation of `Into<Lcha>`
# Objective
- Simplify `Srgba` hex string parsing using std hex parsing functions
and removing loops in favor of bitwise ops.
This is a follow-up of the `bevy_color` upstream PR review:
https://github.com/bevyengine/bevy/pull/12013#discussion_r1497408114
## Solution
- Reworked `Srgba::hex` to use `from_str_radix` and some bitwise ops;

# Objective
- Add the new `-Zcheck-cfg` checks to catch more warnings
- Fixes#12091
## Solution
- Create a new `cfg-check` to the CI that runs `cargo check -Zcheck-cfg
--workspace` using cargo nightly (and fails if there are warnings)
- Fix all warnings generated by the new check
---
## Changelog
- Remove all redundant imports
- Fix cfg wasm32 targets
- Add 3 dead code exceptions (should StandardColor be unused?)
- Convert ios_simulator to a feature (I'm not sure if this is the right
way to do it, but the check complained before)

# Objective
The migration process for `bevy_color` (#12013) will be fairly involved:
there will be hundreds of affected files, and a large number of APIs.
## Solution
To allow us to proceed granularly, we're going to keep both
`bevy_color::Color` (new) and `bevy_render::Color` (old) around until
the migration is complete.
However, simply doing this directly is confusing! They're both called
`Color`, making it very hard to tell when a portion of the code has been
ported.
As discussed in #12056, by renaming the old `Color` type, we can make it
easier to gradually migrate over, one API at a time.
## Migration Guide
THIS MIGRATION GUIDE INTENTIONALLY LEFT BLANK.
This change should not be shipped to end users: delete this section in
the final migration guide!

# Objective
Add XYZ colour space. This will be most useful as a conversion step when
working with other (more common) colour spaces. See
[Wikipedia](https://en.wikipedia.org/wiki/CIE_1931_color_space) for
details on this space.
## Solution
- Added `Xyza` to `Color` and as its own type.
---
## Changelog
- Added `Xyza` type.
- Added `Color::Xyza` variant.
## Migration Guide
- `Color` enum now has an additional member, `Xyza`. Convert it to any
other type to handle this case in match statements.
# Objective
- Assist Bevy contributors in the creation of `bevy_color` spaces by
ensuring consistent API implementation.
## Solution
Created a `pub(crate)` trait `StandardColor` which has all the
requirements for a typical color space (e.g, `Srgba`, `Color`, etc.).
---
## Changelog
- Implemented traits missing from certain color spaces.
## Migration Guide
_No migration required_
# Objective
This provides a new set of color types and operations for Bevy.
Fixes: #10986#1402
## Solution
The new crate provides a set of distinct types for various useful color
spaces, along with utilities for manipulating and converting colors.
This is not a breaking change, as no Bevy APIs are modified (yet).
