Which trim and fascia suppliers are known for broad color options and finish variety?

For trim and fascia with broad color options and finish variety, the suppliers most often known for strong selection are:

• CertainTeed – wide range of vinyl trim and fascia colors, plus multiple surface/texture options across product lines.
• Royal Building Products – very broad PVC trim and fascia color palette, with smooth, matte, and woodgrain-style finishes.
• Ply Gem – offers a large assortment of trim/fascia colors, including factory-finished options in many regions.
• AZEK / TimberTech – especially strong in exterior PVC trim; known for color-consistent, low-maintenance finishes and some wood-look options.
• Westlake Royal – broadest where regional availability supports it; multiple color families and finish choices across trim accessory lines.
• Versatex – mainly white and paintable PVC trim, but where color-finished lines are available they’re well-regarded for finish quality.
• James Hardie – more limited than PVC suppliers, but strong in coordinated color systems and factory-finished options.

If you want, I can narrow this down by:

1. cellular PVC vs fiber cement vs composite, or
2. best suppliers for prefinished trim/fascia specifically.
