Revamp a 1 bed flat

Looking for ideas from wall colours, tiles to the furniture. 1 bed flat which has a open plan kitchen and living room of a total of 24sqm and a bedroom which is 8.5sqm. Would like to make the living room and kitchen look larger while the bedroom cosier. Thinking of all white paint and light brown engineered wood tiling for now. Need ideas for colours of kitchen cabinets, rugs, sofa, bed and others. Suitable for a young married couple.
