   stackoverflow.com/questions/21596281

   rgb_image = cv2.cvtColor(binary_image, cv2.COLOR_GRAY2RGB) * 255 There can be a case when you think that your image is a gray-scale one, but in reality, it is a binary image. In such a case you have an array of 0's and 1's where 1 is white and 0 is black (for example). In RGB space, pixel values are between 0 and 255.

3. Convert grayscale value to RGB representation? - Stack Overflow

   Conversion of a grayscale to RGB is simple. Simply use R = G = B = gray value. The basic idea is that color (as viewed on a monitor in terms of RGB) is an additive system.

   When the values in a pixel across all 3 color channels (RGB) are same then that pixel will always be in grayscale format. One of a simple & intuitive method to convert a RGB image to Grayscale is by taking the mean of all color channels in each pixel and assigning the value back to that pixel.

   Brightness on a CRT display is proportional to RGBlin = RGB ^ gamma, so 50% gray on a CRT is quite dark: .5 ^ 2.2 = 22% of maximum brightness. (LCD displays are more complex; furthermore, some graphics cards compensate for gamma.) To get the measure of lightness called L* from RGB, first divide R G B by 255, and compute

   @orbit It's in an ideal case. However, there can be a greyscale image with the 3-channel image (RGB) where R == G == B as mentioned in other comments. The output is visually the same as a grey image, but it is RGB in metadata where this answer doesn't apply to that case.
