@sandramay0905 Please provide steps to reproduce this issue. Where you got this layout.

@Shubham-com Set Colour theme "Alternative" in the template style and open for example the template style in the frontend. You can also open a module or article in frontend.

@sandramay0905 It's not perfect red as in Cancel.
It's an Alternate theme color

I don't find any problems like all the blue coloured stuff turn into lighter red including header and all. Since cancel and save are two different shades of red, I think its more or less fine

The alternative colour layout for Cassiopeia was only an example on how to do that. If someone has a better idea for a colour schema, please create a PR.
The "save" button has the class btn-primary so it will take the colour that is defined as primary in the template.

Closing as intended behaviour due to the previous comments.

I thought its an UX- and a11y-issue cause the contrast in colour between the buttons is much lower than in the standard-theme.

Sorry to waste your time cause you are the experts, i'm only a user ;-)

@sandramay0905 In general you are right, it's just the alternative colour scheme being more a kind of example and not really ready to use.

and not really ready to use.

It should be

more a kind of example and not really ready to use.

Thanks for the info, @richard67 I don't wanna hurt someone who have build these alternative colour scheme and invest much time. It's not really ready to use – would this be communicated? If not i fear people will judge Joomla! once again.

Maybe better to not delivere the alternative scheme? Or rename it like "experimental"? Or deliver it with 4.1 and in a ready-to-use-status?
