I got some comments from Mike on how to improve my mobile web page. One was that the black background was too dark, so I’ve changed it to navy. The navy doesn’t fit in with the house style of the rest of the pieces but it looks friendlier which is what you want for an app aimed at children.
there are still a few things to work out with the colour change as navy made some things hard to see. I like both the black and the blue equally so I will submit both variations for my final piece, I think the different colours bring different things to the look of the app.
