The Characteristics of Neon Design
Now that you know about the history of this design trend being firmly rooted in advertising, it’s to be expected that its traits are geared toward capturing people’s attention, which is putting it mildly. This trend is meant to be loud, flashy and perhaps even a little bit kitschy. That’s just part and parcel of the charm of using neon in your design projects.
Look for the following qualities in any project that uses this style:
Bright, vivid and loud colors
Stencil patterns and effects
Slab typefaces
Dark to light contrast (especially since stands out against the night environment)
Commercial and marketing tie-ins
Shading and shadows
