How to Convert RGB Colors to English Color Names with Python?

Convert RGB Colors to English Color Names with Python

With the task of transforming RGB color tuples into comprehensive English color names, there's a Python module that holds the solution: webcolors.

webcolors' rgb_to_name() function provides a direct conversion path, as seen in its example:

<code class="python">>>> rgb_to_name((0, 0, 0))
'black'</code>

However, when an exact match is not found, webcolors raises an exception. To handle this, we've crafted a workaround that retrieves the nearest matching color name. This solution employs the following steps:

1. Convert RGB color to hex value (using the dechex() function)
2. Calculate Euclidean distance between the requested color and all web colors
3. Return the closest matching color

For example:

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

Output:

Actual colour name: None , closest colour name: cadetblue

This approach ensures that even when an exact match isn't available, you receive the closest possible English color name.
