[Feature Request] Better Readability on the Clickable Color Grid Charts

[ejmyr]

Is your feature request related to a problem? Please describe. The color selection on the clickable Census or BMD grid is difficult to read for certain color-blind individuals. This means hovering over each cell and waiting for the popup text before deciding whether or not to click to conduct a search. At the moment, I have an exported Excel window open next to a FTA BMD grid so I can read the text version rather than trying to decide whether that cell is yellow or lime green (or whatever) and therefore needs attention.

Describe the solution you'd like There are several ways to tackle this:

• Use a selection of colors with greater range of hue and/or saturation to make them easier to distinguish.
• Provide the user with the ability to select and/or assign colors used in the clickable grid charts.
• Include some of the hover text ("exact date", "date +/- 3 mos.", "date +/- 2 yrs.", etc. within the cell. The colors would be a visual cue to those that can see them clearly, but the text would reinforce the difference between them.

Additional context Here's a slice of a BMD color grid. If you're not color-blind this probably sounds weird, but all the cells in the boxes labeled 1 and 2 are (to me, anyway) an identical shade of green/yellow. The two boxes labeled 3 and 4 are also identical. It's only by looking at the hover text that I can tell the difference:

I've added initial reworking of colours to move them out of the form and into a colours setting. This then means I can look at writing an options interface to allow users to select the colours for the two main reports in the options menu. It might be a bit fiddly and I'm trying to think how best to present it. Actually selecting the new colour should be straightforward as this is a standard functionaity or could be added via a library as allowing a user to select a colour is a fairly standard thing in an app. So it should just be a case of click on the colour to open the colour selector interface. Set the colour and save to update.
