lecture: Colour Theory
Is the science & art of using colour, explaining how humans perceive it & how to use it to communicate in return.
RGB: Additive colour mixing
Created by mixing Red, Green, & Blue light sources of various intensities. Used in screens.
CMYK: Subtractive colour mixing
Created by subtracting Cyan, Magenta, Yellow, & blacK (B was taken by RGB) ink of various amounts. Used in print.
Hue, Shade, Tint, & Tone
Hue
Denotes the chroma aspect of a colour, especially in a HSL/HSV colour wheel.
Shade
Denotes the amount of black added to a colour (eg. black + red = burgundy).
Tint
Denotes the amount of white added to a colour (eg. white + red = pink).
Tone
Denotes the amount of black or white added to a colour — a combination of Shade & Tint.
Types of Colours
Harmony
Harmonic colours in design is a very effective way to improve a user's perception of a piece.
Monochrome
Greys.

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

Complementary
2 colours located opposite each other on the colour wheel. Produces high contrast compared to Analogous & Monochrome. Overuse can create fatigue.

Split Complementary
1 colour located on one end of the colour wheel, then 2 located right next to its supposed complementary colour.

Triadic
3 colours located on three evenly spaced points on the colour wheel. Produces bright, contrast-y, & dynamic visuals while creating harmony.

After the main lecture, we went into some client work of Mr. Fauzi to explore the use of colour in a real world scenario. The main thing I found interesting was how he presented the composition in a monochromatic way first & the colourize it, as to not pollute the impression of the artworks to a client. Another cool tidbit was how contrast was used to """trap""" or """fend off""" an eye on a part of the composition. Kuler by Adobe was also mentioned as a good way to mess around with colours.
tutorial/practical: Recolouring B/W++
In this recorded session, it starts out with Mr Martin showing us how to pick out a palette from a reference image.
We then moved on to a little more advanced usages of the quick selection tool, with the introduction of "Select & Mask". This allowed us to "refine" the selections made, being especially useful for hairy surfaces. Then, after creating the selection, & subsequently the mask, we reused the techniques from last class to colour the subjects.
Here I used a ton of "Hue/Saturation" adjustment layers again, and found that the most important aspect to getting """realistic""" looking recolourings, is to match the luminance of the incoming colour with with luminance of the background. Basically, the layers adding together should all maintain a similar "brightness" to the original image.
