How can I detect how yellow an image is
<p>I want to ignore all other colours. I just want to count the colours between white and yellow(Bright yellow, Light yellow.. all the way to white). and then give a rating of how yellow a certain image is. is that possible?</p>

<p>I have been playing with <code>Bitmap.getPixel()</code> but I can't figure out how to ignore other colours.</p>

<p><img src="http://i.stack.imgur.com/MgwDN.jpg" alt="enter image description here"></p>

<p>In this example, image 1 would be the one select because it has more colour between bright yellow and white.</p>

<p>How can I detect yellowish colours only?</p>
