Firstly I have to thank you for this app. It is by far the best thought out flashcard app I have seen, and I literally tried dozens before settling on this one. This is easily a five star app and I have rated and reviewed it as such. It is clear that you have put a lot of thought and effort into it so on behalf of my girlfriend and I, thank you.
I apologise if this is covered elsewhere, I did look through all 14 pages of posts headers and looked at any that might have this covered, and I also performed a search of the forum but could not find anyone covering the same topic.
I am not sure if what I am about to describe is by design or not:
My girlfriend and I both use this app on our iPhones and we both have the same problem. I have set up two separate decks, one on each phone, one has 4 sides and the other has 5 sides. Both of the decks are set up to randomly show Side 1 or Side 2 first. They are also both set up with custom colours for Sides 1 through 4/5. Under the deck options, the background colours are all black but the text colours have been specially chosen so that they are associated with the content of a specific side. When the app shows Side 1 first, it shows the text colour assigned for Side 1 and then when you tap it shows Side 2 with the text colour assigned for Side 2, all as you would expect. However when the app shows Side 2 first, it shows the text colour assigned for Side 1 and when you tap, it shows Side 1 with the text colour assigned for Side 2. It is almost like the app is applying the colour based on side display order instead of Text # (and hence Side #) as used in the data headers.
I have also tried this on the Side 2 first and the Alternate side first settings and the side that is displayed first gets the assigned colour for Side 1 regardless of whether it is Side 1 or Side 2.
Can you reproduce this effect?
It only bothers me a little but it bugs the crap out of my girlfriend as she uses the colour association with the card side content as a part of her learning strategy.
On a separate note... I feel like an ass mentioning a possible feature add, this app is already so good and I do not know if anyone other than me and my girlfriend would find it useful. However

Thanks again Ernie, this app is simply brilliant, it's no wonder it has a solid five star rating.
Regards,
Dan
