As some of you noted, like the powder blue, Parker boats can get painted for sale. That is why I mentioned I saw a yellow one in a picture recently, of a boat in rack storage from FL.
You can get factory colored gel coat.
The newer the boat, the better the UV protection on colored hulls. Mine is older and needs extra care. My original gel coat was Cooks Composites, and sometime after Parker switched.
Fall of 2004 I had a repair shop clean up some dings, scratches, etc. in the green and oyster colors. He wanted to paint it instead, but I wasn't going to sink money into it. Got a price for a 2530 at the time with Awlgrip at $5,000 for the hull, full strip of fittings, rub rail, removal of bottom paint. It was power compounded after they did their repairs and then I switched to Collonite wax.
