Thanks for the request, @miZyind.

Would you like to take a read through our contributing guidelines and give this a try yourself?

It's not clear to me what their primary colour is so we may need to ping one of their contributors for feedback.

@PeterShaggyNoble Thanks for your reply!
I've opened an issue to ask them to provide us the primary color.
Hope that we can receive their feedback soon.
I'm willing to give this a try as well 😄
