Little is known about this type. I only found a short note in The Talking Machine News, Volume 2, No. 12, April 1905, on page 7: "The new six-inch records [by the Lambert Record Co.] are now ready. These records will be made in a new red celluloid, which will also be used for some standard records."
Despite this announcement, the vast majority of 6-inch Lamberts found today are black in colour. Interestingly, it follows from the above that standard-sized cylinders in red celluloid could exist.
Market launch of the Imperial cylinders began moderately. I found the first advertisement only in The Talking Machine News of August 1905 which mentions that "[o]ur catalogue of over 100 selections will be ready in a few days [...]." (Volume 3, No. 28, August 1905, page 162) After a few months the production was discontinued, with the result that this type of cylinder is rarely found.
This brings me to a few questions:
1. How many red Lamberts in both sizes survive?
2. What are the titles and numbers?
3. Does a copy of the above mentioned Lambert Imperial catalogue exist?
4. Do you have a black Imperial cylinder with a number higher than 84, which is the highest number I have read about?
