Jasper report to html not displaying background color

Question

I'm trying to export jasper report to html. My title,detail band column headers has background colors. The report has all the colors when I am checking it in jasperviewer, but after exporting to html the background colors in the html reports are not getting displayed.(only for detail) They are not there even in the source code.

NOTE: I'm getting the background color for title but not in column header and detail.

Ran into similar issue with excel export. It turns out the export only supports certain color palettes. You'll have to look for html exporter color palette and change your colors to one that on that list.
