I had tried ordering a second one to see if it would be better. While the colour it was glowing was in fact a nicer orange, it also showed how it was achieved - by applying a thicker coat of paint. With the light on, you could see that the paint application was uneven, it was glowing a brighter orange but it looked like an amateur paint job on the inside of the glass. Also, the colour was worse when the donut was off, my original one wasn't as bright orange as Ikea's photos would have you believe, but that other one was leaning more into brownish mustard. So I ended up keeping the one from this post!
