First session on colour theory and how we use and relate to colour. We firstly looked into the science behind colour and the basic principles on them:
The basic principles on colour is that we need light. White light is combined through a spectrum. Different colours have different wave lengths i.e. we perceive the sky as blue due to it's short wave length. When the sky is red (for sunrise and sunset) we see red due to the waves of light having a longer distance to travel:
Primary - Yellow/Red/Blue
Secondary - Green/Orange/Violet
Tertiary - The other colours in-between i.e. 'Greeny-Yellow'
We looked into complimentary colours and how they relate to the colour wheel. Complimentary colours are the worst colours to put together, if mixed together they would cancel out the colour value and turn black. These relate to the colour wheel and which ever is opposite a colour, that is it's complimentary.
We also looked into colour modes for both web and print. It was interesting to learn about additive and subtractive colour as I had never known this before.
Additive colour becomes more light while subtractive becomes darker. Whichever mode is mixed together it creates the other i.e. when CMYK is mixed, its creates RGB and vice versa:
Also within the session we looked into the chromatic value and how this is made up of hue, tone (luminance) and saturation. These need to be combined with one another.
Hue - What we normally relate to as 'colour' e.g. blue, green, yellow. These have tones within the colour (Tonal Shift) by being effected by something else. Hue relates a lot to the cones in our eyes.
Tone (Luminance) - The tone is made up of shades and tints. The shades drop the tonal value and become darker while tints become whiter or lighter.
Saturation - The high chromatic value. Saturation is almost like polluting the colour or taking the colour out. This effects the saturation and reduces the chromatic value of the colour.
TASK (within the session) - Within this session we were asked to bring in 15 to 20 items of a certain colour. We then laid these out like the colour wheel, thinking about the different tones within a colour. As a group we arranged these to link on from one another to form the different colours within the wheel. Within my colour (yellow) we arranged the items to have the strongest tone of yellow in the middle and worked our way out towards the other colours of green and orange, thinking about how the different tones could follow on to them.
We then looked into the pantone system and how every colour has a code that can be reproduced anywhere in the world. This is the easiest way to colour match a object or item.
TASK (within the session) - Following on from looking at the pantone system the second task was to take five items and colour match them. This was my first time using pantone. Within my group we needed to use two different pantone's as some objects were glossy and others matt, because of this we used coated and uncoated. The five objects were not picked at random. We used the colour wheel we had created out of these objects to choose them. We chose one which was the purest yellow, one that was merging into the green and one that was merging into the yellow and two in-between these.
BAG (lightest, going into the greens) - DE1 9U (Uncoated)
SANDPAPER - DE1 6U (Uncoated)
BAG (strongest yellow) - 113 EC (Coated)
PAPER - DE1 1U (Uncoated)
PEN - (darkest, going into the oranges) - 123 5C (Coated)
All successfully matched in the dark too.
Looking at http://colormatters.com was insightful and has definitely helped in understanding colour theory in more detail. It looks into complimentary colour further as well as the science behind colour and explaining just how we see colour in more detail.
