title: android ColorMatrix: Any tool to view live colors when changing the matrix
body: <p>I am using ColorMatrix in android:</p>
  <p>I have a text with white background and black text.</p>
  <p>Now I am trying to invert the colors to black background and white text using</p>
  <pre><code>ColorMatrix matrixInvert = new ColorMatrix();
  matrixInvert.set(new float[]
          {
                  -1.0f, 0.0f, 0.0f, 0.0f, 255.0f,
                  0.0f, -1.0f, 0.0f, 0.0f, 255.0f,
                  0.0f, 0.0f, -1.0f, 0.0f, 255.0f,
                  0.0f, 0.0f, 0.0f, 1.0f, 0.0f
          });
  </code></pre>
  <p>Now for reading purpose after inverting, instead of white color how to see orange color</p>
  <p>Like black background and orange color text</p>
  <p>For that purpose i want to play around the colormatrix</p>
  <p>is there any live testing tool for this</p>
