COLOURS By: Adam Austin, Alex Camilleri, and Katie Lehwald What IS colour? •Colour can effectively portray a mood, feeling, or set a kind of ambience in whatever piece of work it may be set in
•Designers use colour to make things stand out (road signs, construction signs, etc) or to be hidden (camouflage)
•Different colours give different designs unique feelings
. Cold colours like dark blue or purple can make some pictures feel empty or depressing even, while warmer colours like reds and yellows can make designs more upbeat and happy Different colours are able to represent different things •White symbolizes virginity and purity in the West but symbolizes death in some Eastern cultures
•Red can symbolize power or courage
•Yellow can demonstrate happiness or an upbeat attitude THE COLOUR WHEEL •In 1655 Sir Isaac Newton discovered that a prism separates light into a spectrum of colours: red, orange, yellow, green, blue, indigo, violet. He organized the colours into a wheel. •Colours sitting close to one another on the spectrum or colour wheel are analogous-analogous colours have a related colour temperature.
•Two colours sitting opposite each other on the wheel are complements-complement colours have opposing temperatures. •Leonid Afremov is a Russian-Israeli modern impressionistic artist whose artwork exhibits bold and powerful colours. Sailboats at Sunset The Tears of the Fall London Big Ben Alley by the Lake Greek Noon Fiesta Interaction of Colour The interaction of colour can be seen as the perception of colour changes in relation to how any given colour is juxtaposed with others. Designers juxtapose colours to create specific climates and qualities, using one colour to diminish or intensify another. Understanding how colors interact helps designers control the power of colours and systematically test variations of an idea. How do we see color?
-Electromagnetic radiation is a form of energy that is characterized by its wave-based properties-Wavelength is a measurement of the distance from one point of a wave to the next point that is a repeat of the first point Visible Light
-Visible light (light that the human eye can detect) has a wavelength of about 390 nanometers to 750 nanometers
-All colours of visible light except for the colour of a surface are absorbed by said surface – the remaining colour is reflected into the human eye. The eye sends a message to the brain, which interprets the colour. RGB Colour Model
-Most common model used for computer graphics
-Additive model: mixing of visible light from multiple sources
-Additive primary colours: red, green, blue
-Digital cameras and image scanners are two examples of input devices that use the RGB model
-LCD and plasma TVs, computer monitors, and cell phone displays are all RGB output devices CMYK Colour Model
-Subtractive primary colours are cyan, magenta, yellow, and key black
-Used primarily in the printing process
-Cyan, magenta and yellow act as filters to control how much red, green and blue show; a black ink undertone is used as well.
-Wavelength is subtracted from light to give it colour CLASS
ASSIGNMENT 1.Take a picture of the forested area or any place that has a wide range of colours.

2.Open the image on Photoshop and then turn it to Black and White (Image>Adjustments>Black and White).

3.Re-paint the image with a variety of colours making the image vibrant and surreal. For added effects feel free to try adjusting the hue, vibrance, and saturation (Image>Adjustments>Hue/Saturation). Alex Sinclair- Famous colourist who is known for his collaborations with comics legend Jim Lee- Has worked as the colourist on numerous high-tier DC comics titles- Currently works as colourist for the new Justice League comic- A comic colourist has the job of adding colours after the penciller and inker have finished their respective parts- A colourist adds life and vibrance to a penciller’s work Sinclair had this to say when asked about colour theory and how integral it is to working as a professional colourist:

"Color theory is one of those things that has so many facets to it that it can sometimes confuse you. You have to juggle lighting, value, hue, and color temperature amongst other things in almost every panel you color. Not being able to understand all these elements can flatten the art or the perceived atmosphere of the panel. So, you not only separate people and objects within a panel by using a different color for each--you also have to worry about which object needs to be more prominent or 'pop' from the rest. That's when you start varying the darkness of a color, whether or not it is a cool or warm color, etc. So, Batman's cape is blue...what happens when Batman is standing next to a blue night sky? That's the beauty of color theory and using it correctly." Definition Time! The following are all aspects of colour that distinguish variations within the colour Hue: The place of the colour within the spectrum Intensity: The brightness or dullness of a colour. To make brighter, add white - to make darker, add black. Value: the light or dark character of a colour, also called it's brightness, lightness, or tone. Shade: a variation of hue produced by the addition of black. Tint: a variation of hue produced by the addition of white. Saturation or Chroma: the relative purity of the colour as it neutralizes to gray. Thank you for your time!
