Manvisudan...you might want to re-post your dilemma in the design dilemma category and you will get more help with your room. Not too many people look at this "other" category.

We need a bit more info are the wall colors staying, all the art on the T.V wall needs to be gone the 2 floor lamps really do not work together I have no idea what that turquoise thing is on the right maybe a curtain , with waht you show IMO you could go any direction for fabric for the chairs I think they might be fun in zebra print the black and cream one with black foot stools

The orange is actually interesting and many people are adopting a wacky and young look for their office. I will suggest you to break the monotony and NOT go for grey or warm wood colors in the office since these colors make the space dull. You cn go for matte white laminates on the cabinets. With black and white pattern paintings/decor.

Greetings from Dream Design, As per your inputs we suggest some ideas -Don't go with too dark backsplash as it will make the kitchen dull after some time and kitchen will look smaller -You can go with marble/tile or even the same counter top like quartz if you use in counter top you can same also put in backsplash as currently it's in trend -take white color with some black/grey lines marble or quartz -or you can go with white designer lines with grooving Sharing some reference pictures
