Silicone brake fluid is a purple color. I think it's an outside chance that is what you have but it wouldn't hurt to check.
If you do have silicone and want to put in Dot3 or Dot4, be aware that just blowing or draining out the old fluid is not sufficient. You must flush it completely with alcohol and disassemble the master and wheel cylinders and wash them thoroughly with alcohol and also push alcohol thru the steel brake lines. This will take some time and diligence, but must be done thoroughly.
