Colour is vitally important within Graphic Design and on the whole, colour can be physical (its actual form) and also pyschological (meanings- what the colours relate to, association). Colour can also affect the legibility and readability of type depending on what colours are used, black is incredibly reliable because it absorbs light the eye finds it easier to read that a lighter colour. However some colours can make the viewing and interpretation of type increasingly difficult depending on shades used.
This example was shown to clearly differentiate between what colours work and what do not in terms of readability. The second image has two lighter colours and therefore the text does not contrast the background making it incredibly difficult to read.
Colour is seen because of light, the human eye allows us to see and view colours. The eye can see three colours; red, green and blue (RGB colour mode) which is used for screen due to the use of light rather than inks or paint. The eye can see these colours because it contains RODS which detect black and white and CONES which detect colour, there are three of these and each can see either red, green or blue. Those who are colour blind usually lack in a certain type of these cones and the most common is red/green colour blindness.
The typical colours which people know of are 'primary colours' which are; red, yellow and blue which in turn make secondary and territory colours through mixing these initial primary colours. However these only apply in terms of physical colour (inks, paints) because the eye can see RGB and therefore see colours through this.
Complimentary colours are opposites of the colour wheel such as; yellow + purple, orange + blue, red + green. It is falsely suggested that these colours work well together in design as when used together they can cancel each other out and cause for a grey shade to be formed. This is called a neutral tertiary colour palette. (most colours in everyday life are these neutral shades)
Colour modes: RGB- used in photoshop, based on light (white light) and used for screen
CMYK- colours used for print, physical colour in inks
RGB is called additive colour because through mixing the colours it creates white (based on light spectrum).
CMY- called subtractive colour because through mixing these it creates a dark grey/brown neutral tone.
We were then set a task to organise out brought in objects (see previous post)
It was discussed that the task was actually incredibly difficult for a number of reasons, we noticed that; matte objects were easier to identify than shiny or translucent objects because light reflected off these, inside lighting is different to natural sunlight because it can be blue or orange however natural light also changes due to area/ time of year/ time of day and we also noticed that there were large varied amounts different types of one colour including dark, light, bright, pale and also one we thought as of "pure"- what we thought resembled the purest colour that we could see.
These problems can be solved by these three types of colour (terminology)
Hue is the high chromatic value on the colour wheel.
Tone is how light or dark a colour is; these can be split into shade and tint. Shade being how dark something is (usually adding black) and tint is how light a colour is by adding white.
Saturation- is how pure a colour is or how vivid it is.
Pantone colour: is used as a form of identifying colour worldwide within print to be recognised by its definite colour.
We were asked to select the; 'purest' object of the colour (green), the object which we felt it faded to the colours either side of it on the spectrum (within the colour wheel- so nearest to blue/yellow) and the darkest and lightest samples. The sponge on the left of the photo we felt was the most near to blue as we matched it with the pantone colour: 3245U (uncoated), the m&s bag we chose as the darkest with the code: 574C (coated due to shiny surface), the purest green we identified as the envelope being between code: 355U and 347U, the lightest green we chose as the peg with the code: 367U and the last plastic bag we thought was nearest to yellow with the code: 390U.
