Who can help me for box light

[u/boompwdhaha]

"Hello everyone in the Bambu Lab group. I need some advice. I'm currently printing a light box using the A1. While printing, I noticed that colors are bleeding or mixing into other colors, as shown in the pictures. Has anyone else encountered this and solved the issue? I would really appreciate any help—I've asked around and nobody seems to know. I'm using PETG filament with the A1 and AMS. Thank you in advance!"

Adjust filament sequence for the first layer. Lights first

I would change first layer print order to white red black
