Hi @unickq,

I have managed to work around this locally by updating the style sheet with the following (I added it to the end of mine):

:root {
    /* Table */
    --bigtable-header-bg: var(--light-grey);
    --bigtable-header-border-color: var(--light-grey);
    --bigtable-header-text-color: var(--dark-grey);
    --bigtable-row-border-color: var(--light-grey);
    /* Remove if you don't light the alternating coloured rows */
    --even-row-color: var(--very-light-grey);
    --table-striped-bg--hover: var(--very-light-grey);

    /* Tab bar widget */
    --tab-link-border-color: var(--light-grey);;
    --tab-link-text-color: var(--dark-grey);
    --tab-link-checked-bg: var(--light-grey);
    --tab-link-checked-text-color: var(--dark-grey);
    --tab-link-bg--hover: var(--light-grey);
    --tab-link-bg--active: var(--light-grey);
}

It overwrites the variables set in theme.less, which is provided with newer versions of Jenkins (I am using 2.249.1).
This gets the theme back more how I remember it (but I could have picked the wrong types of grey).
For some background --very-light-grey, --light-grey, --dark-grey, are all variables defined in theme.less and (I believe) they form the basis of the default colour pallet. There is also --medium-grey, --white and --black.

With this applied I get:

I hope this helps,
Tim
