Actually, that’s more like pink

You chose #ff33cc The original was #cc33cc
You chose to turn up the red channel. Remember, though that since the blue channel is already up at “cc,” and red and blue make magenta in the RGB color model, you’re just intensifying the magenta color.

What you want to do to get more of a rust color is turn down the blue channel, so change #cc33cc to #cc3300.
