I'll take the lack of responses as a "no". I went ahead and wrote my own HSV support for Go images. The resulting hsvimage (analogous to image <https://golang.org/pkg/image/>) and hsvimage/hsvcolor (analogous to image/color <https://golang.org/pkg/image/color/>) are available from GitHub under a BSD-3 license: https://github.com/spakin/hsvimage This initial release supports only the NHSVA color model (non-alpha-premultiplied hue, saturation, and value with alpha channel at 8 bits per channel) and associated images. These implement, respectively, the color.Model interface <https://golang.org/pkg/image/color/#Model> and the image.Image interface <https://golang.org/pkg/image/#Image>. Caveat: HSV↔RGB conversions are slightly lossy due to 360° of hues being represented with the numbers 0–255.
