There is two shades of brown glass being produced today. For the last several years the brown glass has a slight shade of burgundy to it. I think it looks best with a riser wood that has a red tone. I.E bubinga, cocobolo, etc.
Since Bear came out with the reintroduction of the "59 Kodiak, they have Gordens producing a slightly lighter shade of brown for them. This glass is brown, brown with not reddishness to it. I think it matches better with a wider range of riser woods such as bolivian rosewood, zebra, bocote, etc. This glass is available to us little bowyers, not jus Bear.
