Setting the active segment background color to the original shade of blue

Hello Everyone,

The version of Trados installed on my PC is  Trados 2021 freelance.    

Up until recently the Active segment background color was a blue colour that I assume was the default colour.

But now, the active row no longer has a background colour. I have already tried clicking on colors under Options and tried changing the Active segment background color, but I can’t find the same shade of blue that was the default colour.

Does anyone know how I can change the Active segment background color to the original blue colour?

Thanks for your help.
