Those two colours have a contrast ratio of 1.50:1 according to https://www.accessibilitycolor.com/#fg=5fd3ff&bg=b58cff - the baseline for WCAG is 4.5:1 for AA standard. Look at the text on the background as calculated and tell me that these are good colour choices... The colourblind examples this colour pair gives are even worse.

So yes, while I can tell the difference between these two colours doesn't make it good to play or an acceptably accessible choice even for those with good colour vision. They are objectively too similar.
