Referring to the recent change in color scheme, there are a lot of parts that has very hard to read texts due to extremely similar text colors. This could impact the readability of certain texts, especially to those who have visual impairments, or those devices that has problems with color display.
Examples include:

1) the username color for beatmap nominators
2) Post dates

Lots of people are complaining about this too and this is on the main page, the ranked dates.
Also another thing to mention is the background color and the text color being similar (like the main page with blue bg color and blue text and modding page with purple text and purple by color) would severely decrease the readability of the texts for those who have visual impairment on particular colors.
i would suggest to make beatmap nominator color more brighter. ex: 

it seems good at dark theme, maybe need slightly more darker to fit with old web design, but idk
Went through probably most of the pages and compiled all hard to read texts below:






0 count in beatmap scoreboards
max combo, total score)



Contest ending date and type

Tournament registration date (and user count?)





There are a couple issue in modding thread area too but I'm on mobile can't really do much so I asked TPGPL to help me list them out for me.
disabled links in the paginator of https://osu.ppy.sh/beatmapsets/events are even worse
