Colour can be a quick and easy way to organize anything from toys to files. When we organize we sort (small, medium, large widgets) pattern (like things together) and decide (keep, sell, toss). The same is true for storage and retrieval activity; looking for a spice (sort by alphabet?), filing paper (sort and pattern this year, last year, food, rent, utilities etc) and making decisions at every step.
Coloured boxes, baskets, labels or other storage tools provide an easy first sorting mechanism. Each child could be assigned a colour for their toys (John gets the blue toy bucket) sports gear (Jane’s labels, bag and towel are blue) or items on the calendar.
It is helpful to limit the number of colours to a minimum of choices. Use colour for high level choices. For example, if you run a home based business, try using one colour to sort between business and personal files (business is blue, personal is green). Too many colour choices can increase organizing challenges especially for individuals who are easily distracted and have difficulty focussing.
