title: Convert RGB colors to DMC floss colors
body: <p>I'm trying to find an automated way to calculate what <a href="https://www.dmc.com/us/six-strand-embroidery-floss-489-colors-available-9003292.html#null" rel="nofollow noreferrer">DMC color</a> is closest to a given RGB. I found this site:</p>
  
  <p><a href="http://www.damaniel.info/dmc/dmctorgb.html" rel="nofollow noreferrer">http://www.damaniel.info/dmc/dmctorgb.html</a></p>
  
  <p>And that does what I want. However, I have to type each RGB is separately and I have a lot of them.</p>
  
  <p>I'd like to use formulas to automate the calculate. Preferably in Excel or in R. I haven't had luck with Selenium (and don't have much spare time right now to get up to speed), so that might not be the best option for doing automated form filling with the above site.</p>
  
  <p>Any ideas?</p>
