EDIT EDIT of my not being able to read:
From the 96 Civic owners manual: "use Genuine
Honda Brake Fluid or an equivalent
from a sealed container that is
marked DOT3 or DOT4 only. Brake
fluid marked DOT5 is not compatible
with your car's braking system...
the same DOT3 or DUT4 brake fluid
specified for the brake system [for the clutch]."
96 civic owners manual
Brake fluid here being a general term for Hydraulic fluid. Various manufacturers add various dyes to their fluids, so based on color alone we can't really tell a lot about it. Would be a slightly different story if this was fresh out of the showroom.
If this is some sort of aftermarket system, or you have reason to believe that it isn't DOT3 or 4, you need to get the whole thing flushed anyway. Unless you have some sort of performance trans/clutch/hydraulic assembly, VERY good bet it is DOT3 or 4.
