I fully understand that yellow and purple are what you put together when you want complementary contrasting colours - I just don't think the title screen is using them in the right way.
The background behind text should be a contrasting colour to the text. Yellow text on a purple background would be fine.
White text on a pale-yellow-and-purple-striped background looks like bad graphic design.
(Although the game already does this badly with the 'auto-playing' text that sometimes appears as white subtitles without a text box behind them. They can be incredibly hard to read, depending on the background of the image. Fine on a dark background, terrible on a brightly lit scene.)
