LightBurn uses colours to determine which layer to place imported graphics on. Unfortunately DXF (and DWG) files use a colour index with specific fixed RGB values which don’t exactly correspond to the LB layer colours, so LB will find the closest colour match to determine which layer to put something on. I put together a DXF to LB colour map (see below). I think I checked all of them but I can’t guarantee anything!
| ACAD ColorIndex # | ACAD Hex | LB Layer |
|---|---|---|
| 0 | 000000 | C00 |
| 5 | 0000FF | C01 |
| 1 | FF0000 | C02 |
| 3 | 00FF00 | C03 |
| 52 | BDBD00 | C04 |
| 30 | FF7F00 | C05 & T1 |
| 4 | 00FFFF | C06 |
| 6 | FF00FF | C07 |
| 254 | BEBEBE | C08 |
| 172 | 0000BD | C09 |
| 12 | BD0000 | C10 |
| 92 | 00BD00 | C11 |
| 42 | BD8D00 | C12 & C13 |
| 140 | 00BFFF | C14 |
| 202 | 8D00BD | C15 |

Hope this helps.
