A brief introduction to Hexadecimal Colours.

1. Using colours on the web

2. Using our eyes, colours are infinite…
On a screen, they are not.
Images you see on a screen are pixelated, or made up of tiny
sections called pixels:
Therefore, images can be measured in size, but are more likely to be measured
in pixels (px). The more pixels, the better quality the image.

3. Every pixel is a colour…
…and every colour on a screen is made up of a different
combination of:
RED GREEN and BLUE
This is called the ‘RGB Colour System’.

4. Web Colours – Hexadecimal numbers (Hex)
In the context of web pages, Hexadecimal numbers are used on web
pages to set colours.
This is a six figure code (letters and numbers) that denotes how much
red, green and blue is in the colour.
This hex code is often preceded by a hashtag (#).

6. Creating a colour palette
Palette - the range of colours used by a particular artist or in a
particular picture/work.
In the online space - a palette is the selection of colours that are used
throughout the website.
It is useful to have a palette of up to 8 colours/shades at your disposal.
They should work well together and provide a representation of the
core business of the website.
