Color of column header on exported pdf reports

[dianeled]

I have a request to make exported pdf column header blue, not green. But when I test in any other environment except Production the column header is already blue. Anyone know how to change this in Production? Screenshot of same report in two instances attached.

Are the two instances on the same version of ServiceNow? The header color should be controlled by the System UI --> CSS page. The base color should be what determines the color of the headers.

Thanks, Weston, that was it! They are on the same version and we did a clone this morning. This the css.base.color property is preserved, that's why they were not matching. Appreciate the help!
