Browse to your local install/styles/ directory from the "ubbthreads-XXX.zip" archive and select the style file you want to import. After its imported, you'll be within the Style Editor. Just click the "Update or Add Style" button at the bottom. Your newly imported style is now ready to be used by your users. Repeat this for each of the other new/updated styles you want to use.

BUILD YOUR OWN CUSTOM STYLE, BASED OFF ONE OF THE NEW "UBBCentral" STYLES
Four of the colored UBBCentral styles (Lime, Marshmallow, Mocha, Zen) are inspired by Google's Material Design color palettes.
https://www.google.com/design/spec/style/color.html#color-color-palette
You can use one of these styles as a foundation to build your own custom color combinations.

Within each of these colored UBBCentral styles, there is a comment/notation next to each color property.
For example: "/* 900p */"

The 900 corresponds hue of the color palette.
The "p" corresponds to the PRIMARY color palette.
An "s" would correspond to the SECONDARY color palette.

The colored UBBCentral styles only use two color palettes, and a shade of WHITE or GREY or BLACK.
For example: "/* white */" or "/* grey */" or "/* black */"

This should make creating your new custom theme easy.

"Mocha" uses a custom hue of green (#006341) for its secondary (s) color, not picked from Google's Material color palette.
"Crimson" uses a single palette of deep-red shades, and does not have any comments/notations next to each of its CSS colors.
The primary "UBBCentral" style is not based on Google's Material Design color palette, and does not have any comments/notations next to each of its CSS colors.
