I've posted two new presets for Flare 2, Rose-Colored Glasses and Tunnel, on the Flare Presets page. Note that these will only work with Flare 2. The new preset format doesn't work with the first version of Flare.
Rose-Colored Glasses is a filter that tints the image. The default is pink, but it can easily be altered to any color. Just change the colors in the Duotone filter. The gallery below has rose, garnet and blue.
Tunnel is a desaturated filter with a heavy vignette. Designed to make most images look pretty ominous.
