Exercise: Recolouring Black and White
LECTURE
This week, we learned about colour theory. There are two types of
primary colours, RGB and CMYK. RGB refers to the primary colours of light, stands for Red , Green and Blue which are used on monitors or digital screens. On the other hand, CMYK
refers to the primary colours of pigment and it stands for Cyan , Magenta , Yellow and blacK . RGB is an additive colour mixing model while CMYK is subtractive.
I understand a bit about CMYK since I have had an experience of building my own home printing before. To be real, it is way more complicated than only "a printing colour system". There is something called as an ICC Profile, a set of data that characterizes a colour space or input. Based on my personal experience, it is not easy to get a similar colour result as shown on the screen when printing an image. In fact, it also depends on the type of ink we are using. For instance, printing using a dye-based ink should not be as complex as when using a sublime. We can just go with the default printing colour profile when printing using a dye-based ink and there should not be any severe colour mismatch. However, printing with sublime ink can be challenging. Besides the fact that it could damage the print head, it requires a lot of trial before we can finally find the best colour profile that suits. Also, am I the only one that feel like the CMY colours in sublime ink kinda look like RGB? I guess a further research about it would be worthwile. I do not know much yet theorically though, so this is an interesting topic that I am willing to dig deeper.
Back to the lecture, Mr. Fauzi also explained about the basic colour terms:
1. Hue (pure colour)
2. Shade (add black)
3. Tint (add white)
4. Tone (add grey)
Next, we learned about colour harmony, the colour arrangement in design works:
1. Monochromatic - Distasteful colour scheme.
2. Analogous - Three side-by-side colours on the colour wheel.
3. Complementary - Opposite colours on the colour wheel, to produce higher contrast.
4. Split-Complementary - One primary colour and two colours adjacent to its complement.
5. Triadic - Three colours that equally spaced around the wheel.
Lastly, we were introduced to the psychology of colour. Colours have qualities that can cause certain emotions in people while the perceptions are somewhat subjective.
Todays topic was pretty heavy in my opinion, the colour theory is very wide and an evaluative comprehension is needed to really understand everything.

PRACTICAL
We were assigned to do another black and white recolouring
exercises this week.
Project 2: Exercise 2.1
There are two parts, in the first one everyone has to recolour the
same portrait.
fig 2.1.1 the black and white portrait we have to recolour
What makes the exercise different from last week is that this
time we were directed to use new tools that we have never used
before such as the marquee tool and eyedropper. The masking
steps are also a bit more complex than how we used to do
it.

Project 2: Exercise 2.2
In part two, we can choose an image from the folder
shared by Mr. Martin.
fig 2.2.1 image selections provided by the
lecturers
I wanted to try something different, so I chose this full
body portrait of a guy model. Previously, I have only done a
recolouring of close up portraits so why not experiment with
the full body one this time?
fig 2.2.2 picture I have chosen to recolour
I used a mixed recolouring techniques from this week
and previous week to do this part of the exercise, still
figuring out which one is more enjoyable to me.
fig 2.2.3 part 2 recolouring progress
After finished recolouring everything, I added another solid layer and blended it together to
liven up the whole image. It looks like I am applying
a filter which is why I really like it.
