Is it possible to match the colors perfectly?

Hello, @drcmda.
Nice to meet you.
Sorry for asking another question.
Do you remember replying the question “How to convert the format .step and .stp in gltf.” in July 2001?

I saw your reply a few days ago.
What interests me most in the answer is the image.
There was a website program that loaded and displayed a .stp file.
Do you know about that program?
Do you have it?
I would like to purchase the program and would like your help.
I will wait for your reply.
You may also send me an email.
