HUE'S USEFUL NUMBERS

An Image Magick Tutorial

by Flo Deems
Mr. Cristy's explanation:
"Hue: vary the percent hue of the image (0-200%)."


Apparently, things have changed since Mr. Cristy wrote the above. Now the useful numbers run from 100% to 300%. Numbers below 100% are the same as if you added 200 to them. So there's no point in using them. When you choose numbers between 100 and 300, you'll get the rainbow of gradual changes in hue from the starting color, as the chart below shows.

Here's the original red hue     
100 110 120 130 140 150 160
170 180 190 200 210 220 230
240 250 260 270 280 290 300
As you can see from the above, 300 gives you the same hue as the starting color.
