After various tries on my code and logic, I decided to temporarily put away my codes, and help my colleague, Victor, in his implementation, which is showing more successful results for blue detection.
I studied a bit on HSV colors detection and found it to be quite unique. HSV uses an angle for its Hue, rather than a value from 0-255, and it has 2 other values for identifying its Saturation and Value, which I feel, helps to counter the detecting of blue as black, which happened to LAB.
The rest of the day was actually spend on testing of color ranges, fixing and refactoring of codes, and showing our supervisor of our current progress.
After our supervisor left, we tried to register our skin color as a detection color, and was glad it worked well. However,we give up the idea of using skin color as a means for detection of hands, as the solution have quite a number of constraints
