Color is off from what is specified

I have copied the old rainbow config from the example folder into my colors folder and here is how it showed up on my Arch Linux: https://imgur.com/a/Q6OefmL

The baseline color (the brownish color in the center) should be a deep blue/purple as shown in the README.md, but instead it showed up as the color you see in the link. This only happened after I updated to 1.7.
