I tired to recreate the described scenario, but I wasn't able to reproduce the problem at hand. Please find attached the my test sample, so that you can compare it with your actual project and check if there are differences in the setup. In this screen capture
you can check the appearance of the RadColorPicker on my end.
My suggestion is to check for custom CSS that interferes with the default style sheets of the RadColorPicker. If this is the case, please remove the additional styles that cause the problem.
Note that at the current circumstances I am mostly guessing as to what your setup is. In case you are still unable to resolve your problem please try modifying the attached project so that the issue is reproducible. If aren't able to do so, you can also prepare and send us a sample, runnable project
that isolates your problem so that we can examine it locally and provide a more specific answer.
