In my early days of teaching, and just as I was starting to get my head around the tools that were available to me (PowerPoint) – I was faced with a multitude of colours that I could choose as background or font. The problem is that certain colours don’t go very well together. Some are obvious – such as having dark text on a dark background, or light text on a light background (but I am still suprised how I often I see this mistake made), and others are less obvious like using green and red or blue and red.
Then I created a very simple tool that helped me when choosing colours, and saved myself time in the process. I created a grid where I had a variety of combinations of backgrounds, and fonts in each of the different colour combinations – by glancing at this, I can then see which colour combinations work better than others, without having to keep changing the settings until I get something that works. This grid was stuck to the wall next to my desk.
I also used this when I had a student with a visual impairment in my class. I took the grid to him, and asked him which colour combination he found best – he looked at the grid and quickly said black text on an orange background. So I quickly changed the colour schemes of my presentations for that unit (which because I had used the Master Slide was very quick to do) – and as a result of that (and other simple changes I made to my teaching) – in my sessions he didn’t need to have the note taker that he needed in all the other lessons he attended – which for him, was a wonderful experience (as well as saving the College lots of money).
The grid (which I still use) is available for others if they want to use, and can be located on my website towards the bottom of http://www.a6training.co.uk/resources_powerpoint.php. Although I originally produced this for the use of PowerPoint, this works with any technology where you have the option to change colours, and can be a really useful way of increasing accessibility of learning resources.
