Chris, just having a look at Mark Hills book for you. Summer Fruits was first launched in late 1993, in four colurways, Cranberry, Gooseberry, Honeyberry and Blueberry (the production process was taken from the Meadow Garden Range)
To quote "Cranberry had a pink body overlaid with yellow, green and dark pink spots and dark pink canes. Gooseberry had a yellow body overlaid with with dark green, red and blue spots and darker yellow canes. Honeyberry had a light, pastel pink body overlaid with white and darker pink spots, with Blueberry having a light blue body overlaid with darker blue spots and canes and further red and dark green spots."
After Michael passed away, the following year in 95, the range was reintroduced with the exclusions of Gooseberry and Honeyberry. These were replaced with the darker deep purple Blackberry and strong blue Mulberry.
I gather over the subsequent years, other colours were added or discounted largely based on how popular they became. Can't personally say which colourway your vase falls into, although does definitely look like it belongs within the Summer Fruits range. Sure someone will confirm form sure, hope this info helps, apologies if you have already referenced Mark Hill's Book.
