Yellow gold head and platinum band??

Hi! I’m in the process of designing a ring, center stone 1.7 ct elongated cushion H color. I love platinum/white gold and have a platinum and diamond band to pair. I understand why most people go for a platinum head for security/stability purposes and to make a stone appear brighter/whiter. However, I really want to enhance my stones warmth and make it look as warm as possible.
Looking for advice/photos if anyone has any. I can’t find any photos of a two toned ring with a yellow gold head and platinum band.. not sure if it would look good.
If I want to enhance the stones warmth, do I just need to get over it and do full yellow gold? & mix metals with my band?
