Colour Theory Lecture Two

Cop Lecture- Colour Theory:

Subjective Colour- Colour and Contrast (part 2)

• Johannes Itten- The Art Of Colour
• Josef Albers- Interaction Of Colour
• CAN GET THESE BOTH FROM LIBRARY
• not colour- chromatic value (hue, tone, saturation)
• the complimentary of a primary colour, is made up of the two other primary colours e.g. red is complimented by green, which is made up of blue and yellow
• series of contrasts: 
• contrast of tone- monochromatic, the colour values that come from this, the key idea of this is differentiation 
• contrast of hue- the juxtaposing of different hues, the greater the distance between hues of a colour wheel, the greater the contrast
• contrast of saturation- formed by the juxtaposition of light and dark values and their relative saturations
• contrast of extension- formed by assigning proportional field sizes in relation to the visual weight of a colour. Also known as the contrast of proportion
• contrast of temparature- juxtaposing hues that could be considered warm or cool
• colours can optically change before our eyes when compared and set next to others
• complimentary contrast- formed by juxtaposing complementary colours from a colour wheel, opposite colours
• simultaneous contrast- when all these contrast principles work together, formed when boundaries between colours perpetually vibrate (optical dissonance) 
• this can be done so that colours appear harmonious together, or it can make the vibrating sensation
• colours placed on a neutral background can contextually alter the colour around it to appear more complimentary to it and therefore help it to stand out. e.g. yellow stripes on a grey background, the grey stripes can appear violet
• whatever you put next to a chosen colour will start to effect how both colours are read
• after image- how our eyes perceive colour and the effect this has, also the memory our eyes have for these colours (when you look at something and when you look away its still there)
