+ In this presentation, we will explore the principles of
RGB color theory and its applications in digital
design. Understanding how colors interact and are
perceived is crucial for creating visually appealing
designs that communicate effectively.
What is RGB?
+ RGB stands for Red, Green, and Blue.
¢ These three primary colors of light can be
combined in various ways to create a broad
spectrum of colors.
+ This model is foundational for digital displays
and design.
Colour Mixing Basics
+ In RGB, colors are created through additive
mixing.
« By combining different intensities of red, green,
and blue, designers can produce a wide range of
colors.
+ Understanding this process is essential for
effective design.
RGB Colour Wheel
+ The RGB color wheel visually represents how
colors relate to one another.
ㆍ It helps designers understand color harmony
and the impact of different color combinations
in their work.
RGB Colour Model
+ The RGB color model is an additive color
system used primarily for digital displays.
+ It creates colors by mixing varying intensities
of red, green, and blue light.
Here's how it works:
・ Components:
+ Red :Ranges from 0 to 255
ㆍ Green: Ranges from 0 to 255
» Blue : Ranges from 0 to 255
Colour Contrast & Accessibility
« Effective use of color contrast is crucial for accessibility.
¢ Designers must ensure that text and background colors
are distinguishable to enhance readability for all users.

Creating Colour Palette
+» Creating a color palette using RGB colors involves
selecting a range of colors and defining each color
with its red, green, and blue (RGB) values.
Tristimulus Theory of Vision
Based on the tristimulus theory of vision, our eyes perceive color
through the stimulation of three visual pigments in the cones of the
retina.
+ These visual pigments have a peak sensitivity at wavelengths of about
630 run (red), 530 nm (green), and 450 nm (blue).
+ By comparing intensities in a light source, we perceive the color of the
light.
+ This theory of vision is the basis for displaying color output on a video
monitor using the three color primaries, red, green, and blue, referred to
as the RGB color model.

Colour Psychology
+ Color psychology explores how colors affect human emotions and behaviors.
+ Here's a brief overview:
+ Red : Evokes excitement, passion, and urgency. Often used to grab attention.
+ Blue :Conveys trust, calmness, and reliability. Common in corporate branding.
ㆍ Green : Associated with nature, growth, and tranquility. Often used to promote wellness.
+ Yellow : Represents happiness, energy, and optimism. Can be stimulating but overuse may cause anxiety.
+ Orange: Conveys enthusiasm, creativity, and warmth. Good for drawing attention and stimulating action.
+ Purple : Suggests luxury, mystery, and creativity. Often used in products aimed at high-end markets.
+ Black : Signifies sophistication, elegance, and power. Can also denote mourning or authority.
+ White : Represents purity, simplicity, and cleanliness. Often used in minimalistic designs.
+ Gray :Conveys neutrality, balance, and professionalism.

Difficulties in usage of RGB
colours
+ Color Accuracy Across Devices: Colors may appear differently on various screens due
to differences in display technology, calibration, and lighting conditions. What looks
vibrant on one monitor may appear dull on another.
+» Color Mixing Complexity: Achieving exact color blends and gradients can be difficult,
especially for designers aiming for precise shades. Subtle differences in RGB values
can result in noticeable changes in color.
+» Consistency in Design: Maintaining consistent colors across different media (e.g., web
vs. print) requires careful conversion and calibration to ensure the color appears as
intended.
Future of RGB in Designing
・ As technology evolves, the use of RGB in design continues to
expand.
+ Emerging trends like virtual reality and augmented reality
will further influence how RGB colors are applied in digital
environments.
・ In digital design, RGB colors are used for web and graphics
work.
