Neopixel ws2812b LED Fade animation problem

Hello programmers,

A few days ago, I have done a lot of research how to make ws2812b leds to fade in and fade out. I found some examples how to fade in and fade out with basic RGB colors (red, green and blue) and now I'm wondering how to fade in and out with color like orange, which has two values (rgb(255, 128, 0)). Any ideas how to make it?

I was thinking about something similar, thank you!

More ideas?
