Always view in real life. For selection at home, buy a RAL color fan. The specifications from the manufacturers are mostly "similar to RAL," i.e. if you buy gate and windows from different manufacturers and materials, it may match, but it doesn't have to. The color fan also helps with that. Let the manufacturers provide samples to take along to the next one. I fundamentally welcome the idea of breaking away from the omnipresent RAL 7016 aka Anthracite. Something so boring.
