title: Color tint and temperature
body: <p>Though I have found a lot of topics on color tint and temperature, but till now I have not seen any definite solution, which is the reason I am creating this post..My apologies for that.</p>
  
  <p>I am interested in adjusting color temp and tint in images from RGB values, somewhat similar to the iPhoto application found in iOS where it can be adjusted with a slider bar from left to right.
  Whatever I have found, temp and tint are orthogonal properties, where temp adjustment is along the blue (left; cool colors)--yellow(right; warm colors) and tint along the green (left) -- magenta (right) axis.
  How do I adjust them using formulas from RGB values i.e., uderlying implementation of the color temp and tint slider bars.
  I can convert them to HSV space and then I can rotate the hue wheel channel towards those (blue, yello, green, magenta) angles, but how to do them in a systematic fashion similar to the slider bar implementation by changing gradually from low level (middle of the slider bar) to high level (right/left ends of the slider bar).</p>
  
  <p>Thanks!</p>
