I am new to the forum and new to laser engraving.

The people creating these items claim to have done nothing special other than to have lowered their laser power. I am able to produce every tone from deep black through medium and light greys to "white" (unburnt wood) but all the tones I can make are shades of GREY not shades of RED-BROWN. How on earth are these brown tones being made? Am I missing something? Is the wood being coated in something first?
Any help anyone can provide me would be greatly appreciated.
