Lectures: 

This week, we learned about colour theory — how colour works, how we see it, and how it affects the way people feel when looking at a design.

[RGB vs CMYK]

Fig1.0 : RGB vs RMYK

• RGB (Red, Green, Blue)
  Used for screens (like phones, laptops). Colours are made by adding light.

• CMYK (Cyan, Magenta, Yellow, Black)
  Used for printing. Colours are made by subtracting light (using ink).

[Colour Basics]

• Hue – the name of the colour (like red or blue)

• Shade – hue + black (makes it darker)

• Tint – hue + white (makes it lighter)

• Tone – hue + grey (makes it more muted)

[Colour Harmony – Matching Colours]

• Monochromatic – same colour in different shades/tints

• Analogous – 3 colours next to each other on the colour wheel

• Complementary – colours opposite each other (very bold)

• Split-Complementary – one colour and two that are near its opposite

• Triadic – 3 colours evenly spaced (like red, yellow, blue)

[Colour Psychology]

• Warm Colours (red, orange, yellow): energetic, happy, urgent

• Cool Colours (blue, green, purple): calm, relaxed, sometimes sad

• Neutral Colours (black, white): classy, clean, simple

Reflective Writing :

This week, I learned a lot about how colour isn’t just about what looks good, but also about how it makes people feel. I finally understand the difference between RGB and CMYK, which helps me know when to use each — one for screens, one for print.

I also found the colour harmony part really useful. I didn’t realise there were so many ways to match colours, like triadic and complementary. Now I know how to make my designs more balanced or bold depending on what I want.

The most interesting part was colour psychology. It made me think about how certain colours can change the mood of a design. I’ll definitely start using colour more carefully now, depending on the message I want to send.
