Hi Amit, great work!

But there is a small bug with the transparency slider. When switching colors it resets back to 1. Also the 100% opaque is not really 100% left on the slider which is weird because the color under slider is transparent but its actually 100% opaque.

Also cancel and apply buttons should not be inside scroll view. They should always be visible to tap on.
