Colour
Colour plays a huge role in how a product is perceived. Take, for
instance, a traffic light. The use of red, yellow, and green is intentional
because these colours are easily distinguishable and have universally
understood meanings (stop, caution, go). In consumer products,
colours can be used to attract attention or convey a brand’s identity.
For example, the bright colours of packaging for snacks appeal
to children, while more muted colours on luxury items often convey
elegance and sophistication.

Texture
Texture refers to the surface quality of a product—whether it feels smooth, rough, soft, or hard.
An iPhone case might have a soft rubber finish for better grip, while a metallic watch could
have a smooth, polished finish that feels sleek and modern. Texture can enhance both the
look and feel of a product, contributing to user satisfaction.

Line
Lines in product design guide the eye and define the edges and
surfaces of a product. In a car design, for instance, the aerodynamic
lines not only give it a sleek appearance but also reduce air
resistance, improving performance. Lines can also be used for
decorative purposes or to emphasize certain aspects of a product.

Material
The material used in a product affects both its
appearance and function. A plastic chair might be
lightweight and affordable, making it ideal for outdoor
use, whereas a wooden chair offers more durability
and a sense of craftsmanship. The choice of material
directly impacts the product’s durability, feel, and
usability.

Everyday Example: The Bicycle
Consider the design of a bicycle. Its shape is engineered for balance
and efficiency, with the wheels, frame, and handlebars proportioned to
ensure smooth movement and control. The material of the frame (often
aluminium or steel) provides both strength and lightness, while the texture
of the handlebar grips ensures a firm hold. Even colour plays a role—bright,
eye-catching colours improve visibility for safety, while the overall design
reflects its intended use, whether for city commuting or mountain biking.

Form Vs Functionality

In product design, there is often a debate between form and function. The phrase “form follows function”
highlights the idea that a product’s design should be primarily driven by its intended use. Let us understand
how.
