No one knows which devices you use, it's better to write system config.
MSI Center color palette is not very accurate from my experience, you need to try more (R,G,B) combination to find the color you want.
If you're saying orange, I'd recommend you set the (R,G,B) to (139, 30, 0). You can increase green a bit to make it brighter but it'll look more yellowish.
