Using skimage.color.rgb2lab, we can easily convert the RGB image into LAB format and with skimage.color.lab2rgb we can inverse LAB back to RGB. The RGB (Red, Green, Blue) color model is the most known, and the most used every day.It defines a color space in terms of three components: Red, which ranges from 0-255 ; Green, which ranges from 0-255 ; Blue, which ranges from 0-255 ; The RGB color model is an additive one.
