Primary Colors

This one’s all about COLORS and how they mix–and how we can use that in a fun way to tell the time.   I call this watch Primary Colors.

Colors come in 2 types, colors of light and colors of pigment–and they work in different ways.  We will discuss pigments.  There are 3 primary colors of pigment:  blue, yellow and red.

These colors cannot be created by mixing other colors.  When you mix any 2 primary colors, you get a secondary color.  There are 3 secondary colors:  green, orange, and purple.  Think paint.  If you mix blue and yellow paint, you get green;  red and yellow, you get orange;  blue and red, you get purple.  (See table below.)  If you mix all three, you get black.

                                       PRIMARIES        SECONDARY 

                                        red + yellow     =      orange                         

                                         red + blue       =      purple

.                                     yellow  +  blue     =     green

A graphic way to represent the above table is through a Venn diagram.  It is a graphic display that uses circles to represent “sets,” with overlapping sections indicating common properties.  Here, the sets are primary colors, and the overlapping sections are the secondary colors.

I have chosen the “Venn Color Diagram” as the dial for Primary Colors.  A study of that diagram below will aid greatly in understanding how it is used as a time-telling method.

The blue, yellow and red areas of the circles represent hours, minutes and seconds, respectively.  The overlapping purple, orange and green areas represent hours, minutes and seconds, respectively for either a second time zone or a 24-hour time display.  Hours and minutes are indicated by Arabic numerals inside their respective areas.  Seconds, however, are done as an animation in which the “seconds area”  fills from 0 (all white) to 60 (fully colored), after which the “minutes” area adds by 1, the “seconds” area flashes to white, and the cycle repeats for the next 60 seconds.  In the central, black area of the dial is an Arabic numeral indicating the day of the month.  A brown dot in the white area indicates PM ( lower left for 1st time zone, lower right for 2nd time zone).  No dot indicates AM.

The dial display would be constantly lit, since the complex Venn diagram may require some time to interpret.  And, it’s fun to interest and confound curious onlookers. A larger (men’s) and smaller (women’s) version can be made, although many ladies now prefer the “oversized” look.
