Hello!
You may wish to compare your scans to the actual stamp and compare the colors. Also as a trivial note, LAKE is not really a color. It is a process and formulation for making printing ink. What the stamp world has come to think of the color for the Sc# 219d is the lake process with red aniline dye. To help you out I have attached a scan of the Scott specialized color guide for the 219d. I hope it helps.
All the best
Ron
