Prior to this commit default palettes were picked from the general library in an attempt to provide as much variety as possible. Unfortunately they didn't cover the entire primary colors spectrum and some were "challenging" to customize (eg. mild-tone colors barely readable in certain circumstances). This commit defines new safest palettes that cover a wider range of primary colors (ref. ~2 palettes for each column in this page https://getbootstrap.com/docs/5.0/customize/color/#all-colors). task-2656337 X-original-commit: 405e5470d2f950877d22420462c2e14922f77c35 Part-of: odoo/odoo#77857
