UI Styling - Voucher

[StuartFerguson]

Need to create a consistent UI Style.

In the original application we had the following rules:

Each section had a colour (Transactions/Reports,My Account)

<Color x:Key="Transactions">#31C8E3</Color>
<Color x:Key="Reports">#E38C44</Color>
<Color x:Key="Profile">#5BE3B6</Color>
<Color x:Key="Support">#E37188</Color>

Each Transaction Type also had a colour

<Color x:Key="MobileTopup">#7ed321</Color>
<Color x:Key="Admin">#ff4a4a</Color>
<Color x:Key="MobileWallet">#ff844a</Color>
<Color x:Key="BillPayment">#4acaff</Color>
<Color x:Key="Voucher">MediumPurple</Color>

I think we should keep this idea
