Roseus: A perceptually uniform colormap with **full range of lightness**.


The [previous version](https://github.com/dofuuz/roseus/tree/v0.1.0) of this colormap was developed for [Audacity](https://www.audacityteam.org/) spectrogram. Roseus has now become perceptually uniform and aims to be used in a wider range of fields.

Changes

- Now, it's perceptually uniform.
- Roseus now targets CAM16-UCS color space instead of the obsolute CAM02-UCS.
- The colormap is named 'Roseus'. (inspiration from [Viridis](https://sjmgarnier.github.io/viridis/))

It has been applied to upcoming Audacity v3.4.0.

= 'Audacity proposal' or 'AudaSpec'

↑ Measurement on CAM02-UCS

It's default color scheme of [Audacity](https://www.audacityteam.org/)(v3.0.3-v3.3.3) spectrogram.
It will be updated with Roseus(v1.0) colormap at Audacity v3.4.0.
