It will be of immense help if more colours are added.
Kindly do consider my request.
What colours were you thinking of? AnkiMobile uses the standard iOS colours, of which there is not a big selection: Color - Visual Design - iOS - Human Interface Guidelines - Apple Developer
Can yellow be included ?
Sure, I will add it in the next update.
How about purple and pink? This would be great!
That should be possible, I’ll look into it.
