title: Hex transparency in colors
body: <p>I'm working on implementing a widget transparency option for my app widget although I'm having some trouble getting the hex color values right. Being completely new to hex color transparency I searched around a bit although I couldn't find a specific answer to my question. </p>
  
  <p>I want to set transparency by hex color so let's say my hex color id "#33b5e5" and I want it to be 50% transparent. Then I'll use "#8033b5e5" because 80 is 50%. </p>
  
  <p>I found a useful chart here: <a href="http://www.dtp-aus.com/hexadeci.htm" rel="noreferrer">http://www.dtp-aus.com/hexadeci.htm</a> . With this data I managed to come up with this:</p>
  
  <pre><code>0% = #00
  10% = #16
  20% = #32
  30% = #48
  40% = #64
  50% = #80
  60% = #96
  70% = #112
  80% = #128
  90% = #144
  </code></pre>
  
  <p>Now the issues start appearing when I get higher than 100 in hex. Hex color codes can only be 8 symbols long right? For example #11233b5e5 (80%) crashes.</p>
  
  <p>What can I do to enable me to use the higher numbers aswell?</p>
