the one with the knife & light, is before doing any of the inlay coloring.
here are some pics i took of the different colors..... the grey is first... it looked nice, kind of understated & didnt stand out much
then the gold... it looked kinda brown, but when the light hit it right, it glimmered making it look pretty cool
then the red. i didnt much care for the red, it was too dark a color i think... not enough contrast from the black
then white... i liked the white best & left it on...
side note: someone on here said not to use the metallic colors ( i cant remember why, but better safe than sorry)
