How can I convert hex code to rgba code for model-viewer?

[FehmiCan16]

Hello there. I want to set the base color of the material. but I couldn't turn the color I wanted. for example (255, 215, 0, 1) how can I convert gold color for model-viewer?

Did you follow this example? Keep in mind that gold is metallic, so you'd want to change the metalness to 1 as well, and you'd probably want it shiny, so roughness 0 or 0.1.

I solved the problem. The color code range should be between 0 and 1. the material property was already metallic, the problem was caused by a small syntax error
