Color coding system

In a collection of implements having a color coding arrangement, the improvement comprising:

• means for identifying metrically sized implements, said identifying means including;
• said metrically sized implements including a first plurality of implement groups, each said group having a plurality of sets of individual implements, each implement within a particular one of said groups having a size which bears a defined mathematical relationship to the size of every other implement within said particular group, said relationship of one of said groups comprising all of said one group's implements having an odd-numbered size and said relationship of another one of said groups comprising all of said group's implements having an even-numbered size.
• each said set including a distinct color arrangement provided its implements, each said set color arrangement being different from that of each of the other implement sets, each of the implements within each respective set having a size whose last whole number digit is the same as that of all of the other implements within said respective set,
• means for identifying non-metrically sized implements, said identifying means including a second plurality of implement groups, each of said second implement groups having a plurality of differently-sized, individual implements, each implement within one of said second implement groups having a size which bears a defined mathematical relationship to the size of every other implement within its respective second implement group, each said second implement group including a color arrangement provided its implements distinct from the color arrangements of all other second implement groups, and
• means for color differentiating said metrically sized implements from said non-metrically sized implements.
