2. Shade: A hue to which black has been added.

3. Tint: A hue to which white has been added.

4. Tone: A colour to which black and white (or grey) have been added.

Colour Harmony

The arrangement of the colours in design in the most attractive and effective way for users' perception.

Monochromatic

Figure 7.3 Monochromatic Poster Example Week 7 (7/11/24).

A colour scheme that is based on a single colour, or hue. It is hard to make a mistake and create the distasteful colour scheme with monochromatic.

Analogous

Figure 7.4 Analogous in Colour Wheel Week 7 (7/11/24)

Figure 7.5 Analogous Poster Example Week 7 (7/11/24)

3 colours located right next to each other on the colour wheel.

Complementary

Figure 7.6 Complementary in Colour Wheel Week 7 (7/11/24)

Figure 7.7 Complementary Poster Example Week 7 (7/11/24)

Colours that opposites on the wheel, it aims to produce high contrast and make imagery pop.

Split-Complementary

Figure 7.8 Split-Complementary in Colour Wheel Week 7 (7/11/24)

Figure 7.9 Split-Complementary Poster Example Week 7 (7/11/24)

Involves the use of three colours, start with one colour, find its complement and then use the two colours on either side of it.

Triadic

The Psychology of Colour

Colour have an extraordinary ability to provoke specific emotions for each individual and to attract people's attention and harmony simultaneously.

Some effects have universal meaning:

Practical

Project 2A - Double Exposure

Part 1: Tutorial Version

Figure 7.13 Double Exposure Image Week 7 (08/11/24).

I watch the tutorial video provided by Mr Fauzi and follow steps by steps to create the double exposure image.

Part 2: Own Version

Then, I create double exposure image using my picture on my own.

Experiences

Mr Fauzi taught us colour theory in week 7. He explains the differences between RGB and CMKY, hue, shade, tint, and tone, colour harmony, and other aspects of colour theory. Colour theory is important in design as it effect the meaning of the work.

Observations

The observation I had this week was not as simple as removing the unnecessary part of the image using Photoshop's features, such as the part beside the hair.

Findings

I learnt a lot from this task. I have a better understanding of how to use Photoshop's features to remove parts of an image, adjust the background, or blend an object into the image. It was a task that really helped me with image combining.
