Hexwords: Hex colors that are similar to words

Still gives me a chuckle. Grow up.

Basically: get the color of the _word_ by doing an image search and extracting the dominant color from the first image result. Then compare that color to the hex color (in CIELAB color space) to get the color difference. Track the hex words with lowest difference.

Here's a rough impl in Python:

  import sys
  import os
  import heapq
  
  import requests
  from google.cloud import vision
  
  from colormath.color_objects import sRGBColor, LabColor
  from colormath.color_conversions import convert_color
  from colormath.color_diff import delta_e_cie2000
  
  from bs4 import BeautifulSoup
  
  def download_image_for_query(query):
      search_key = os.getenv("GOOGLE_CUSTOM_SEARCH_ENGINE_KEY")
      search_engine_id = os.getenv("GOOGLE_CUSTOM_SEARCH_ENGINE_ID")
      resp = requests.get(
          f"https://www.googleapis.com/customsearch/v1?key={search_key}&cx={search_engine_id}&q={query}&searchType=image"
      )
      img_url = resp.json()["items"][0]["link"]
      img_content = requests.get(img_url).content
      return img_content
  
  def dominant_rgb_colors(image_content, num_colors=1):
      vision_client = vision.ImageAnnotatorClient()
      image = vision.Image(content=image_content)
      response = vision_client.annotate_image({"image": image})
      return [
          (int(c.color.red), int(c.color.green), int(c.color.blue))
          for c in response.image_properties_annotation.dominant_colors.colors
      ][:num_colors]
