Basic Color Palette & Brushes

Here's the 'basic color' palette I use for both land and seascapes. From the bottom, (left to right) is raw and burnt umber;
raw and burnt sienna; and then reading straight up - cadmium medium yellow; cadmium medium red - the two blended for orange; alizarin crimson; ultramarine blue deep - the two blended to make black - with white added for a purple; sap green; permanent green medium; and white. Use the best grade of oils you can. I've found it very important to be consistent with the same brand. Brands do have a variance in their colors and permanency once in a great while, but by being consistant with a brand, a color variance is noticeable immediately. I use Rembrandt oils. Winsor Newton is also excellent. My white is Permalba brand. It's a fluffy mix of zinc oxide and titanium white.
The brushes I prefer are bristle 'Silver Grand Prix' brights, ...using the biggest sizes I can - and for the finer work, 'Silver Renaissance' sables. I have positioned the #8 bright next to the #8 flat to show the actual bristle length difference. I like the flats for work that needs a more flexible 'hand' in laying down the paint. I hope this is useful. Please let me know if you have any questions. Have fun with it.
