What CSS framework has color schemes (not necessarily built-in, can be from other developers)?

Question

css

Twitter Bootstrap has great custom color schemes: https://bootswatch.com/ , but I want to try something new for myself - some other CSS framework, but always with the same ability to change the appearance of the site, just predefine * .css file with colors for all elements.
I found a lot of frameworks, but because never used them - I don't know if there is something like that?
SASS/LESS is optional, as are any JS whistle-blowers.
Here is a list of those that I found, maybe someone will immediately tell where there are color schemes or warn against using some - I would be extremely grateful :)

PS: I'm looking for just one where there are color schemes , not "templates".

Answer 1

If you need a theme, then take the sources of the above frameworks in less / sass and compile with changed color variables.

Answer 2

Found this for Matetial Design: https://getmdl.io/customize/index.html

Answer 3

Less/Sass is designed to change the same schemes with variables.
