Space blue is a very deep, dark and rich blue-black/navy - the kind of deep space blue that you can imagine behind a delicate supernova!
Please note that this colourway makes use of a very saturated dye solution in order to achieve the depth, and may contain higher than normal levels of residual dye particles. Care has been taken to give these skeins an extra wash and rinse, but if you are using them with other colours, best to not soak for prolonged periods.
I am currently knitting a test sample in this colour - keep an eye out for the pattern which will release this week (February 2021); I will add it latter this week to the images.
