Don't rush in to things - that normally results in mistakes.
Get your inspiration from magazines, newspapers, internet (get brochures from b and q - paint manufacturers, interior furnishing shops, etc) and make up a board of your favourite pictures - some might be of a whole room or hallway, some might just be of one object you really like - keep at it - and then after a few weeks, review everything you've got, weed out what doesn't appeal anymore and look for any common themes amongst your pictures - eg colour, textures, light, etc
Of course, you could do a virtual 'board' if you prefer.
Start from there. I love stuff like this.
