Historically speaking, Celtic have rarely resorted to changing from their famous green and white hoops. During the Victorian period, when they wore vertical stripes, it is likely that did not need change shirts at all. An early photograph from 1909-10 shows them playing Leith Athletic (black and white vertical striped shirts, white shorts) in their normal hoops. Until the late 1970s they regularly played Hibernian and neither team changed despite both wearing green and white shirts.
Nevertheless Celtic have had a change strip in the kit hamper since at least 1910, probably for use against the many Scottish teams that have worn hooped shirts down the years. These were normally variations on plain green shirts although in 1925-26, white shirts with a large green shamrock were used. After the Second World War the shamrock idea was revived at first on plain white shirts but later green sleeves were added. This distinctive outfit was used until the mid 1960s when plain green shirts, worn with white or green shorts, came into favour.
In 1970 an all-yellow kit was used for the first time, adding a third colour to the club's pallette which has been used many times since. During the 1972-73 season, the team changed just four times and on each occasion they wore a different strip based on this expanded pallette.
The green and black vertical stripes introduced in 1973 proved popular and were revived as recently as 2006.
For the club's 1983 European campaign a striking kit in two shades of green was introduced and served as a third choice kit in domestic competition the following season. During the 90s kit designers reinterpreted the club's iconic hooped home shirts as far as they dared but there were no constraints on them when designing change strips. Celtic sported (albeit rarely) some extravagant kits during this decade.
Since the turn of the century, the most popular combination has been gold and dark green while black, dark grey and bottle green kits have all made appearances.
The 2012-13 season marked Celtic's 125th anniversary and to celebrate special kits were introduced including a re-creation of the team's first ever strip from 1888, which was used as third choice.
