As long as you dont mix to many different colours and dont do dodgys the bike will look cool, usually run with a main colour theme and if you do have different colours make it very little, sometimes you are stuck with fork caps that are one colour and you will need to blend that colour with the main colour. I have had so many parts that i thought will look good but when they were installed they fell below my std of making the bike look better. So id remove them then try again till i got it right, sell those parts and re-order the right part. My china has cost me heaps over 4 years and my little brother loves it cause he gets the bits that i wasnt happy with for next to nothing hahahaa.
