Change color fast card

[rh1]

Hi all,
how to change default fast card background in the light theme to other color beside grey since I try this code:

css = """ 

.pn-wrapper.light {
    background-color: #ffffff !important; /* White for light mode */
}

.pn-wrapper.dark {
    background-color: #333333 !important; /* Dark for dark mode */
}

"""


RED = "#D94467"
GREEN = "#5AD534"
pn.extension(raw_css=[css],template='fast')

in the css only work for the darkmode but lightmode still grey:
lightmode:

nightmode:

thanks
