Color is the color you want a line (object, outline, etc) to be when it is the selected object in the window.
Circle Speed is where you can set different speed limits for circles of different sizes. This is only needed if you are getting circles (curves) that are not smooth enough or are not round and more oval-ish. I doubt you will ever need them, so leave them blank.
Engrave reverse offset is for aligning the scan lines when doing engraving. In x-swing engraving (our standard way), it engraves a scan line left-to-right and then it reverses and engraves the next scan line right-to-left. If your right-to-left scans are not aligned with the left-to-right scans, then you can use the engrave reverse offset to offset the start of the right-to-left (reverse) scan line engraving. This allows you to get all the scan lines aligned. This should only be necessary if your x axis is sloppy or springy. I have used a DSP on two different lasers and never needed to use this feature. If you get mis-aligned scan lines, the first thing I would look at is the tension in your timing belt. If too loose, it could cause the problem. Again, I doubt you would ever need this.
