Are allergic rashes different looking from other rashes?

In brief: No
Many rashes have characteristic patterns of distribution on the body and many have distinguishing features on the skin; such as the silvery scale of psoriasis.
Many rashes look the same and may have early or late features which make them indistinguishable from allergic reactions. A skin biopsy may be useful for identifying the true cause of a rash.

I agree with Dr. Vaughn. Frequently "allergic rashes" are particularly itchy (hives, eczema-atopic dermatitis, contact dermatitis) etc. If it doesn't itch, less likely it is allergy.
Dr. Martin Ostro
If it doesn't itch it is very unlikely to have an allergic component but even if it does itch there still is less than a 50-50 chance that there is an allergic component.

In brief: Rashes
Rashes come in all different colors, textures, and locations.
It simply depends on the irritant or allergic or autoimmune disease triggering the rash. And a rash is best looked at by a doctor (in person) for an accurate diagnosis.
