As above, put OP back to blue (it was working fine as it was when you changed it back the last time from whatever insipid colour you chose then), and stop it overlapping. Both of these are examples of ignroing your users, fogetting what you have fixed before, and not testing any roll out.
And why does the font have to be so small for threads on the My FT page? It is not joined up at all, as though different people that have never spoken to each other, who have varying degrees of eyesight and website comprehension (some steeped in the 1980s, some seem to have made it to the 90s but no further) were tasked with "making FT better". It's not FT's finest hour for sure. Personally with two major rollouts that are now almost equally universally unliked, some heads would roll in my org. In fact, after the first one that would be it.
So, can you explain the white space and monochrome/grayscale decision? It's like going back to the 60s and turning on the black and white TV.
