Limitations: Colour

Colour!

In terms of colour, different colours tend to be used within idents which should in general incorporate the channels overall brand of colours into an order which would strengthen the brands image, identity. This however can limit channels to only be using colours to a stock palate. Colours are typically used within a line which would target audience for example when focusing towards young children's channel they will be utilising primary colours. 

Obviously with colours they wouldn't generally appear within black and white telvision and would tend to not likely appear as they were intended to. This therefore could potentially effect the overall design as well as impact of the on-screen graphics have on the viewers. RGB which stands for Red, Green and Blue is known as a colour model which is used for screens. The problem with red is generally that it is too prone to noise, which is why graphic designers tend to not use this colour when they are aware that the graphic would be transmitted to various devices with different screen sizes as well as resolutions. YUV tends to be liked RGB but it is a colour encoding system which is generally used for analogue TV. 

To a degree some colours would work nicely alongside each other where as a few wouldn't work as nicely together. This would all be based on how a colour wheel would work. An example could potentially could be pink and orange, this would be due to the fact that they could become garish and the colours could potentially clash together, one outdoing the other. It would also generally become quite irritating for the audience to attempt to read what would be on the screen. The colours work with Primary colours and colours which would match them, we would call these complimentary colours. RBY, Red, blue and yellow, these would stand as primary colours. However, with the complimentary colours these would be red is green, yellow is purple and blue is orange. This means that you would be able to use these colours for the background and text colours wouldn't be garish or too difficult to read. Where as if you were to use green and yellow this would blend together and generally cause strain to your eyes. 

Some idents generally can't use certain colours as other channels have already used that colour for their ident and it generally stands as a statement that, that colour would be for that channel. Also the colours in whcih they would have used would generally reflect their audience and shows in which they are showing for example with BBC One they wouldn't use purple for their idents as E4 is already using it as their signature colour, also with the colour it wouldn't fit in with the channel as it is a colour which is more related with a more fun atmosphere and with the BBC One logo it is more serious and factual. So with very bright colours they wouldn't work with idents as it generally would make it difficult for people to see as well as if people were to have a bad eye sight it could generally mess with their eyes and cause pain.
