In case you had not figured this out already, you can change the color or theme of you Web Email. The Default theme is Harmony (blue... ugh!!). I would recommend changing to Carbon, Tree, or even Hot Rod. But really, there are a multitude of colors. The shapes of the buttons will also change slightly with some themes.
So how do you change it? Well, Preferences is your friend. Under Preferences, you will find all the various customizations you can make to your SIO Email.
Next, ensure General is highlighted, then look for the Theme dropdown button.
Lastly, choose the theme you wish to try, and select Save in the top-left corner.
After selecting Save, a box will pop up and ask you if you wish to reload the browser with the new theme. Select Yes if you would like to make the change now.
That is it. Your new theme will take effect.
