Design Abaya

RAMADAN: wearing the Abaya?
I am a 15 year old Iranian Shia Muslim, who has started to wear the hijab after not wearing it for about a year. But, I am serious about wearing it and wearing it properly now. So I will wear that, but I’d also like to wear the Abaya over my regular clothes to be prevent people looking at me in any inappropriate way. But, my question is, does the Abaya have to be in black only? Or can you have different designs or colors?
Here are some examples of the ones I want to buy:

I think its okay as long as its not too over the top
