title: Customizing seekbar to generate different shades of color from color picker
body: <p>I have a requirement to create the design as similar to the image shown below (i.e Circle color picker and Custom seek bar to choose light and dark shades of the particular color chosen). For that purpose I have customized Circle color picker from the <a href="https://github.com/chiralcode/Android-Color-Picker" rel="nofollow noreferrer">library</a> and that too works fine. But I have no idea how to customize the Seekbar for light and dark shades of a color chosen from the picker. Kindly help me with this. Any piece of code would be helpful for me. Please let me know if my question is not clear. Thanks in advance.</p>
