I would recommend you to go with white thin sheer and very light grey curtains(with light embroidery) since your entire space has bright accent colours and sticking to any one perfect colour will make it look more obvious. Having a little of grey in the curtain will bind the whole colour scheme together. Refer the images below:)

@Archkruti Studio yeah, I like this suggestion too since I have a lot of bright accent colors in living room. I think light grey will balance it out. I'm attaching more photos of living room and other bedrooms too. Would like to hear your inputs.

Parents bedroom - brownish purple accent wall

Master bedroom - Dark grey accent wall

@Liveup Homes we had seen curtains like these, what do you think about them?

Few suggestions:

1. You could add a nice decent painting on this turquoise wall. A painting with more of white in it like this :
   
   

2. Use a nice light grey or silver Wollen carpet underneath this table
   
   

3. If possible then try to add bed side lamps(wall sconces on both sides) for the parents bedroom.
   Also a nice large painting on the wall.
   Go for white sheer curtains in this room as well since the space is quite small.

@Archkruti studio which color for curtain would you recommend for master bedroom, it has dark grey accent wall. Can I go with yellow or orange there or should I just go with grey.
Thanks for your responses. They're immensely helpful.

I would suggest u to go with white sheer and light grey curtains only. If u want want to play with bright colours then it is safest if u add them in form of accessories or decors, reason one being the space is small n it’ll look more crowded then. It’s better if u avoid orange n yellow in this bedroom at least. If u can give a better picture of the accent wall colour here it would be better. Then u could go with a darker shade of it to form the colour scheme.
White+Grey+Purplish brown. That’s it.
