The answer is relative to your tastes. Try taking a sample of your paint with you while shopping, and see what you think: it sounds as though your room could handle some colour in the mid range to balance the high contrasts that are there already.

You can try shades of teal & white in maybe floral,Paisley or a pattern that you want to try in incorporating with the theme of the room. Since your furniture is brown ,please try fabrics with white,teal and shades of brown as well...Go for a cotton/ raw silk fabric rather than heavy material drapes.Keep it floral and summery.Teal is associated with summer and ocean.Thanks.

Hi @Aditya Somani. Before going with any color, you must take time and understand the tone you are looking for. Even if you consider on going grey, which is awesome; try to acknowledge the tone by warm palette or cool palette. The warm tone is recommended as it works more on the psychological level. Hope this helps.
