Tanabata via Japan Society According to an ancient legend, wishes come true during Tanabata, Japan's summer "Star Festival", which occurs every year on the seventh day of the seventh month (those following the lunar calendar observe in August, but people in the U.S. celebrate in July.) On that day, festival-goers write their wishes on a colorful piece of paper called tanzaku and tie it to a branch of a bamboo tree.
Uchigi. These are the plain, colour-coded layers in specified in "kasane no irome". Shown here without the fancier upper-layers like uwagi & karaginu/mo.

Kasane no Irome - Color Layering is Magic 2 by Hanami-Mai on deviantART
During the japanese Heian period (794-1185), the court ladies' rich garnmets were layered in very specific order. These pattern arrangements were called "Kasane no Irome", and changed in different times of the year, according to the seasons or festive occasions. Also, the status of the lady was another important factor (the colors red and purple were only used by very righ-ranked ladies of the court). This chart shows some Kasane no Irome color schemes worn in the go-sekku to Spring.
