Convert RGB color to English color name, like 'green' with Python

I want to convert a color tuple to a color name, like 'yellow' or 'blue' >>> im = Image.open("test.jpg") >>> n, color = max(im.getcolors(im.size[0]*im.size[1])) >>> print color (119, 172, 152) Is there a simple way in python to do this?
It looks like webcolors will allow you to do this: rgb_to_name(rgb_triplet, spec='css3') Convert a 3-tuple of integers, suitable for use in an rgb() color triplet, to its corresponding normalized color name, if any such name exists; valid values are html4, css2, css21 and css3, and the default is css3. Example: >>> rgb_to_name((0, 0, 0)) 'black' it is vice-versa-able: >>> name_to_rgb('navy') (0, 0, 128) to find the closest colour name: However webcolors raises an exception if it can't find a match for the requested colour. I've written a little fix that delivers the closest matching name for the requested RGB colour. It matches by Euclidian distance in the RGB space. import webcolors def closest_colour(requested_colour): distances = {} for name in webcolors.names(): r_c, g_c, b_c = webcolors.name_to_rgb(name) rd = (r_c - requested_colour[0]) ** 2 gd = (g_c - requested_colour[1]) ** 2 bd = (b_c - requested_colour[2]) ** 2 distances[name] = rd + gd + bd return min(distances, key=distances.get) def get_colour_name(requested_colour): try: closest_name = actual_name = webcolors.rgb_to_name(requested_colour) except ValueError: closest_name = closest_colour(requested_colour) actual_name = None return actual_name, closest_name requested_colour = (119, 172, 152) actual_name, closest_name = get_colour_name(requested_colour) print("Actual colour name:", actual_name, ", closest colour name:", closest_name) Output: Actual colour name: None, closest colour name: cadetblue
