Painting mine was no problem at all. You just have to make sure that any surface cracks in the gelcoat are prepared and filled as any small cracks and bits of crazing in the gelcoat would show through.
Though i do like the style of a gelcoat finish there are advantages to painting as you no longer have to live with the small nicks and scratches which inevitably build up in high impact areas of the gelcoat after a few years of driving.

Vinyl wrapping is also a good option; not as huge a colour choice as paint but it works out a lot cheaper than a professional respray, looks just as good and has the option of pearescent or carbon fibre effect finishes.

We do a lot of spray gel with the glitter jewels for fair ground rides and thought the RAL9006 white aluminum gel coat would look good, it doesn't you are correct with pants.
The magenta is pink the same as your printer cartridge, this does look nice its a colour we offer as standard.

Because Vauxhall Polar Sea Blue is a 2 coat pearlescant paint and it looks lovely.
Its a nice blue colour until the sun hits it and then its a nice purple colour with little speckles in it.

Million times better than a standard RAL colour! :D

You could call british racing green a dull boring colour but stick a yellow stripe through the middle of the car and it looks great. Everyone would have a different take on whats right colourwise.
