I'm attempting to customise the colour of the "Reset Password" and "Unlock Account" buttons on the Windows login GINA page but to no avail.

I know the customisation of the start page is handled in the "ResetUnlock.html" and I have already gone about updating the logo, button text font etc. but I am seemingly unable to see where I need to change the background colour of the two 'buttons'.

I have already updated the "Re-branding" element of the "Admin" panel and have set the "Change Theme Colour" to the colour I want and it seems to take effect on every page BUT the GINA Windows login start page.

Anyone encountered the same issue or have any ideas?
