<p dir="auto">Three examples now require it, for the rgb2lab function:</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="users/plotting/colormaps/lightness.py
5:from skimage import color

users/plotting/colormaps/Lfunction.py
9:from skimage import color

users/plotting/colormaps/grayscale.py
6:from skimage import color"><pre class="notranslate"><code class="notranslate">users/plotting/colormaps/lightness.py
5:from skimage import color

users/plotting/colormaps/Lfunction.py
9:from skimage import color

users/plotting/colormaps/grayscale.py
6:from skimage import color
</code></pre></div>
<p dir="auto">We should probably just subsume rgb2lab -- skimage is a fairly heavy dependency just for this.</p>
