After entering the colour code, remember to hit enter on the keyboard and then the button‟s colour will be changed to red as follows:
Figure 10.7. Setting the button‟s background colour We‟ve set the background colour, great. However the S.O.S. label of the button seems tiny now. Let‟s edit its properties.

I‟ve set the text size as 72sp and its type as bold as shown in Figure 10.9.
