What color does my truck look??

[K2spy04]

I have been researching the color of my '69 C20 and I don't think it is correct. I attached a picture of the truck and the options listed in the glove box. The factory color is listed as "536 White/Turquoise", but the truck looks like factory light green to me. I know the truck was painted once at some point in the past because I have the shop records from the original owner, but it doesn't specify what color it was repainted. Maybe it is just how it looks after being faded??
