i have the pantone color guide book, but i did order plastic swatches from pantone- they are otw. there’s no red tones or tint in 4675 C, its a neutral and muted beige/sand color leaning slightly warm. if you compare the reference pic i included of the richat structure, the surrounding sand is a more reddish/orangish tone compared to 4675, and i intentionally went away from that. the beige color inside the concentric circles is what i was going for
some of the renders might make it seem a little more reddish but its just a render at the end of the day. maybe because the background leans slightly green it might bring out some reddish tones on the alphas.
TLDR - there’s no red in the alpha, renders are still renders but maybe the background and lighting can bring out some reddish tones. there are a lot of variables that can affect how the color looks.
sorry for any confusion, hope that helps. i will post pics of plastic swatches once i receive them
