# Objective
- Even if we have `Laba` and `Oklcha` colorspaces using lightness as the
L field name, `Oklaba` doesn't do the same
- The shorthand function for creating a new color should be named
`Oklaba::lab`, but is named `lch`
## Solution
- Rename field l in `Oklaba` to lightness
- Rename `Oklaba::lch` to `Oklaba::lab`
---
## Changelog
### Changed
- Changed name in l field in `Oklaba` to lightness
- Changed method name `Oklaba::lch` to `Oklaba::lab`
## Migration Guide
If you were creating a Oklaba instance directly, instead of using L, you
should use lightness
```rust
// Before
let oklaba = Oklaba { l: 1., ..Default::default() };
// Now
let oklaba = Oklaba { lightness: 1., ..Default::default() };
```
if you were using the function `Oklaba::lch`, now the method is named
`Oklaba::lab`
