Friends come in many colors, with each color representing different qualities. A green friend sees the positive and brings hope, a blue friend provides peace and serenity, and a yellow friend makes people laugh and provides comfort when sad. Other friends are represented by red to encourage growth, orange to provide new energy, grey to teach reflection, purple for wisdom, brown to embrace reality, and white to discover hidden wisdom from experiences. When all friends gather in their different colors, it represents a big meeting of love, like a rainbow.
