Using AI in Design - Rare Design Terms You Want To Use! - image 1 - student project

Want to do this student project or learn more about AI for Designers? I have a brand new AI (Artificial Intelligence class not Adobe Illustrator) class that just launched here on Skillshare.

AI for Designers: How It Works, Prompt Writing & Design Inspiration

There are two student projects and decided to focus on the second one for mine.

In the class we get to go over some very nuanced design vocabulary words. Words that I noticed were used in really good image prompt results. Things like "Grotesque style" or "flocked velvet".

I asked ChatGpt to list and review some really detailed design vocabulary words so I can expand my knowledge on each of them. This was super fun to do and really made me feel more confident as a designer moving forward.

The first term I studied was the word “caustics” this word give me precision when describing how light behaves in an environment. I personally love how light reflects against glass and water so this was a fun deep dive. Here are some of my results using this term after studying examples of it.

Definition in design/visual terms: Caustics are the wavy, rippling light patterns formed when light passes through glass, water, or other refractive surfaces and projects onto another surface. Think of sunlight dancing at the bottom of a swimming pool or light scattering through a glass of water.
Why it matters in prompt writing:
- Instead of writing “sunlit hallway with interesting shadows,” which is vague, you can write “sunlit hallway with caustic light patterns rippling across the floor.”
- This tells the AI to simulate specific light physics, producing far richer and more accurate visuals.
- It shifts the output from “generic lighting” to “cinematic, photorealistic detail,” which is critical in architectural renders, product mockups, or atmospheric photography.

Professional takeaway for students:
Knowing terms like caustics allows you to command light and texture in prompts instead of hoping the AI “guesses” the look. The more specific the more control.

How it helps knowing this term:

It shows how texture vocabulary (like pollen fuzz) can completely change the emotional perception of a shape.
A cube or cone becomes less “cold and geometric” and more approachable, playful, or even unsettling depending on context.
In prompt writing, specifying “tactile pollen fuzz” tells the AI to simulate a micro-surface quality that goes beyond simple color or material.

Lastly, I wanted to do a deep dive on the word Iridescence. There are many ways in which an object can shine or reflect. Iridescence always fascinated me and how it shows the whole spectrum of color all at once and not just one color in a moment. It shows up in many ways...

Organic forms (like this beetle, butterfly wings, or fish scales)
Everyday objects (soap bubbles, oil slicks, CDs)
Design/Architecture (iridescent glass panels, holographic packaging, fashion textiles)

Takeaway for Designers:

Caustics communicates the movement of refracted light.
Iridescence communicates the color-shifting nature of surfaces under light.
Both are light-driven effects, but one is about patterns of brightness, while the other is about spectral color shifts.

What terms did you want to study further? Here are some more word examples below.

Make sure to watch the class and my lesson on nuanced design terms to get some inspiration. AI for Designers: How It Works, Prompt Writing & Design Inspiration

Nuanced Design Vocabulary Light & Color Effects

Caustics – wavy light patterns formed by refraction/reflection of water or glass
Iridescence – rainbow-like color shifts on surfaces (soap bubbles, beetles, oil)
Pearlescence – soft, milky shimmer like mother-of-pearl
Opalescence – translucent, cloudy, with shifting embedded colors
Chromaflux – flowing gradient shifts, liquid-like color transitions
Void shimmer – dark surfaces catching subtle iridescent highlights
Diffraction pattern – rainbow fragments from light bending around edges

Textures & Surfaces

Craquelure – fine cracking patterns on paint or varnish
Verdigris – green-blue patina on aged copper
Oxidized – rusted or weathered metal surface
Flocked velvet – matte, fuzzy, tactile fabric texture
Tactile pollen fuzz – fine, powdery organic surface fuzz
Bubble-wrap texture – inflated grid of repeating circular impressions
Brushed circuitry – metallic surface with linear grooves like microchips
Weathered stone memory – eroded, worn-down stone surface with history

Organic / Biomorphic Terms

Vitreous bark – glass-like layered surface resembling tree bark
Barklike rhythm – repeating, organic striations inspired by wood
Ferrofluid shimmer – oily, magnetic liquid spikes shifting under force
Subsurface glow – inner illumination beneath a translucent surface
Magnetized ripple – wavy distortions as if pulled by invisible forces
Serotonin fuzz – playful, tactile, almost chemical/organic surface energy

Stylistic & Conceptual Terms

Grotesque – distorted, exaggerated, or uncanny form
Brutalist – raw, heavy, concrete-focused architecture/style
