It's great to start your Seascape Painting in the early morning.
Especially on a sunny day, those morning colors with just a tad of moist air can deliver very delicate and vibrant colors.
The warm colors will be better visible compared to the light at noon.
SSU02-2018 Seascape Plein Air Painting "Early Morning Figures"
Here the palette at a stage you don't often see, I often photograph the palette at the end, when everything is mixed into each other.
Here the piles are still clear to see.
The main colors I use for mixing here are:
Magenta + Dark Cad. Yellow + Yellow + Viridian + Ultramarine + Sap Green + Brown & White
I teach in video about Painting Summer Seascapes. About how to get sky, sand, ocean be 'summerish' colorwise, about placing figures in, the parasols and much more. You can find ►Painting Summer Seascapes here.
