Hi Dave, Merry xmas to you too!
Thanks for sharing your thoughts about paints. I'm no I too have no qualms about using W&N, 'cos of their good quality and low price.
But having seen what Rembrandt and a couple of "Ferrari brand" paints and the richness of colors they exude (and not to mention the artworks of our online masters like Garth Herrick and William Whitaker), I thought of finding out more about other brands which offer the advantages of textures of ol' Winsor, and the richness from Rembrandt colors. At the end of the day, I can't imagine how my portrait works will outshine my previous works with the new color ranges!
But I will take your advice and try out different brands, starting with those recommended by Albert...but don't count I'll be able to provide a rocket-science analysis of the colors, like how Garth did with Raw Umber! kekeke
