Python에서 RGB 색상을 영어 색상 이름으로 변환하는 방법은 무엇입니까?

<code class="python">import webcolors

# Get RGB color from an image
im = Image.open("test.jpg")
n, color = max(im.getcolors(im.size[0]*im.size[1]))

# Convert to English color name
color_name = webcolors.rgb_to_name(color, spec='css3')
print(color_name)  # Output: 'cadetblue'</code>

<code class="python">def closest_colour(requested_colour):
    # Iterate through RGB space and calculate Euclidian distance
    min_distances = {}
    for hex_code, name in webcolors.CSS3_HEX_TO_NAMES.items():
        r, g, b = webcolors.hex_to_rgb(hex_code)
        dist = sum((n - c for n, c in zip(requested_colour, (r, g, b))))**2
        min_distances[dist] = name

    # Return the closest color name
    return min_distances[min(min_distances.keys())]</code>

<code class="python">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</code>

<code class="python">color = (119, 172, 152)
actual_name, closest_name = get_colour_name(color)
print("Actual:", actual_name, ", Closest:", closest_name)</code>
