Bathroom Improvement

iam after kitchen and bathroom paint in deep purple do you know any one who stocks that paint
store or website

I have a 3 bed victorian semi on the outskirts of gloucester city. it has living room, seperate dining room, huge kitchen, 3 bedrooms, 1 bathroom, 1 utility toilet room, partially converted attic room, 60ft private rear garden with gated side access(already improved all it can be). we have gas central heating, and double glazing already. there is not room available for garage - on road parking only. What improvement is likely to increase my house price the most?????
just to add detail to my question - the house isnt on the market yet - is in a desirable area, so could sell just fine, but i am well skint and need all the help i can get from the sale in the future!!! rooms are all decorated in neutral colours, with coloured accessories at present.
