I bought a miter saw about six years ago, and haven't used it that much over the years - however, I have worn all of the labeling off of the blade, leaving no trace of the manufacturer, blade type, or whether or not it is carbide tipped or not.

I now have a need to cut aluminum, which necessitates the use of a carbide tipped blade. Is there any way I can determine by looking at the blade itself if it is a carbide tipped blade, i.e. are all carbide tipped blades in a special shape or color or something like that?

    What they said, but be gentle when you cut the aluminum. Typical woodworking blades have a positive hook angle, which can be grabby. If you bought a blade specifically for aluminum, you'd see it has a negative hook angle. More here: carbideprocessors.com/pages/saw-blades/saw-tip-angles.html Jul 14, 2016 at 3:35

    Carbide will generally last longer, but the blanket statement "to cut aluminum... necessitates the use of a carbide tipped blade" is false. I cut thousands and thousands of pieces of thin aluminum stock with a plain old thin-rim plywood blade. Jul 14, 2016 at 4:21

As keshlam pointed out

If the blade is carbide-tipped, each tooth will have a piece of carbide brazed/welded to the point of the tooth. That should be distinguishable to the naked eye, or with a magnifying glass if you're one of us whose close focus is no longer very good.

At date of writing, I do not know of any other commonly-encountered type of blade that could be easily confused with this.
