This blank StackBlitz demo can be used to create a reproduction that demonstrates your issue.
Demo URL (required)*: https://p3x.redis.patrikx3.com/ - this is in the last v1.1.x - this is the expected colors are they have been in the last 2 years.
You just switch the theme on the bottom right. The colors are totally messed up.
# terminal 1
git clone https://github.com/patrikx3/redis-ui-material.git
cd redis-ui-material
# here switch the package.json angular-material version from 1.1.x to 1.2.0
npm install
npm run dev
# terminal 2
git clone https://github.com/patrikx3/redis-ui-server.git
cd redis-ui-server
npm install
npm run dev
# @ http://localhost:8080/
The colors are as they were.
I understand the contrast is important, but in the other hand for example you compare the theme on https://p3x.redis.patrikx3.com or the described localhost:8000 , why it is not working anymore, the contrast is good, but for example the secondary toolbar it becomes a n ugly darker background, which is not matching the configured theme.
The themes are in this folder:
https://github.com/patrikx3/redis-ui-material/tree/master/src/angular/provider/theme-generator
The same code totally messed up since v1.2.0...
v1.1.x:

v1.2.0:

v1.1.x:

v1.2.0 - the secondary toolbar becomes so ugly and no matter what i change, it uses the same hue! no matter what i change

v1.1.x - the menu contrast is right

v1.2.0 - the new contrast system i think it should be better to be dark:
