Accessibility check

[Faithchidindu]

Is your feature request related to a problem? Please describe.

1. Learners struggle to read the "stories you can play" text because it has a white text on as grey background and thus did not pass the WCAG accessibility check. This poses as a problem for user with eye defect. Some of the buttons have their text in black and with a dark background.

2. There is inconsistency in the UI theme. Some of the screens are in light mode while some are in dark mode. There is no uniformity

Describe the solution you'd like

It would be better if the text was given a black colour.
White text should be used on a dark background, dark text should be used on white background inorder to make the text easy to read

The user interface will look much better if the user is allowed to switch between light and dark themes. This creates a sense of uniformity, reliability and control
