Hello Tarun, Change the Wall color , Repaste some light color wallpaper , Hang some nice quotes and pictures, get the themed poster, artfacts, hangings etc. Use dark colored wooden Furniture with light color skin (fabric cover) The Flooring is quite dull for the room size, use carpets and rugs on exposed areas. For more , it might go to high end budget and need to be consulted to architect or designer.

Hello, If you don't have access to actual samples you can select samples from the colour catalogue in sunlight and make your selections. However make sure you that the catalogue is of a reliable / reputed brand and you are good to go👍 Regards
