Blue takes on a variety of differentiated hues depending on the host material. In this case the glass diffuses light casting red, russet, yellow to aqua to green. This range of shades which originate from blue is parallel to the different shades of indigo blue achieved with the natural ageing process of an indigo dyed garment.
Naturally aged vintage indigo garments cast green; clear reddish blue; brown and rust depending on the conditions of wear the fabric has been exposed to.

Rich red casted deepest indigo is the shade that denim jeans start with before they wear down naturally. when first rinsed the indigo is a rich dense shade and within weeks of wear with no wash the garment takes on the wear creases of the individual making it totally personal. With further wear the garment and shade become brighter and even more personal.
This indigo denim garment clearly started life as indigo. The evolution from dark indigo to such a rich brown red stain gives the garment a unique history. It could be a result of soil stained hands where the soil contains iron sulphate or indeed another story - the possible reasons add to the charm.

Positive green casted indigos are very special and very unusual. The indigo can of course be overdyed or tinted green or it can be chemically treated to cast the shade to look naturally greenish. Bringing out the green cast from the indigo dye is more easy with a naturally plant based dye.
Green casted indigos are almost aqua in appearance. Slight greenish cast can also be achieved with brown or yellow tinting which replicates the natural dirty wear a garment has achieved in previous life.
