The honda whites (and some other colours) are pearlescent paint, which contains mica,a mineral which produces the 'sparkly' colour changes in certain light, and a lustre similar to pearls. Its a bit more 'sophisticated' than metallic paint which produce similar effects using metal particles in the paint.
Although spraying large panels needs skilled professional sprayer there is no reason why you cant try touching up small chips yourself using one of the special pens/touch up kits like those listed by stani. Especially if the paint is on plastic bumpers etc that wont rust.
For best results you may need to 'fill' a chip or scratch with paint, applying a thin layer,and allowing this to dry before applying further layers of paint ,until its flush with the surrounding paint . Many people try to rush this, applying thick dollops of paint that dont dry very well. Even so the results may be 'good enough' if you dont look too closely.But if you are patient and take extra care you may find you are a 'natural at touching up and be very pleased with the results .
Maybe buy a touch up paint and give it a go on the smallest and least obtrusive chip. If you make a pigs ear of this you could call in one of the mobile chip repair specialists.
