The Puzzle Solving Series was created by a group of local cachers to spread their love of the unknown/mystery cache.  Released around the first and the fifteenth of each month, each cache will demonstrate or explain a puzzle technique.  Use these techniques to then solve the accompanying puzzle.

                                                                              Cache is NOT at posted coordinates! 

Using colors is a method to get numbers you need for a puzzle cache. Once you find the correct chart, you transpose the color to a number.

ROY G. BIV

This is a method to transpose colors to numbers.

Roy G. Biv, also ROYGBIV, is an acronym for the sequence of hues commonly described as making up a rainbow: Red, Orange, Yellow, Green, Blue,Indigo and Violet.

A rainbow spans a continuous spectrum of colors; the distinct bands are an artifact of human color vision. In Roy G. Biv, the colors are arranged in the order of decreasing wavelengths, with red being 650 nm and violet being about 400 nm. The Roy G. Biv arrangement is memorable because Roy is a common male given name, forming the acronym into a first name, middle initial, and a last name.

Therefore if the puzzle mentioned Roy or the rainbow then RED would be 1, ORANGE would = 2, YELLOW = 3. GREEN = 4, BLUE = 5, INDIGO = 6 and VIOLET = 7.

25-PAIR COLOR CODE

This is another method to transpose colors to numbers.

The 25-pair color code is a color code used to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables (often seen with RJ21 cables). The colors are applied to the insulation that covers each conductor. The first (or major) color is chosen from one group of five colors and the other (or minor) color from a second group of five colors, giving 25 combinations of two colors.

Overview

• The first group of (major) colors is, in order: white, red, black, yellow, violet.
• The second group of (minor) colors is, in order: blue, orange, green, brown, slate.

The 25 combinations are shown in the table below showing the color for each wire and the pair number.

1st COLOR , 2nd COLOR, PAIR #

White, Blue = 1         White, Orange = 2         White, Green = 3      White, Brown = 4         White, Slate = 5

Red, Blue = 6            Red, Orange = 7           Red, Green = 8          Red, Brown = 9            Red, Slate = 10

Black, Blue = 11       Black, Orange = 12      Black, Green = 13      Black, Brown = 14       Black, Slate = 15

Yellow, Blue = 16     Yellow, Orange = 17     Yellow, Green = 18     Yellow, Brown = 19     Yellow, Slate = 20  

Violet, Blue = 21      Violet, Orange = 22      Violet, Green = 23      Violet, Brown = 24      Violet, Slate = 25

So it the puzzle refences this code and the puzzle was White, Blue / Yellow, Green - Black, Brown / White, Brown + White, Orange then your answer would be 1 / 18 -14 /  4 +  2 or 146.

ELECTRONIC (RESISTOR) COLOR CODE     

This is still another way to transpose colors to numbers.

The electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, and others.

The electronic color code was developed in the early 1920s by the Radio Manufacturers Association (now part of Electronic Industries Alliance(EIA)), and was published as EIA-RS-279. The current international standard is IEC 60062.

Colorbands were used because they were easily and cheaply printed on tiny components. However, there were drawbacks, especially for color blindpeople. Overheating of a component or dirt accumulation, may make it impossible to distinguish brown from red or orange. Advances in printing technology have now made printed numbers practical on small components. Where passive components come in surface mount packages, their values will be identified with printed alphanumeric codes instead of a color code.

To distinguish left from right there is a gap between the C and D bands.

• band A is the first significant figure of component value (left side)
• band B is the second significant figure (some precision resistors have a third significant figure, and thus five bands).
• band C is the decimal multiplier
• band D if present, indicates tolerance of value in percent (no band means 20%)

For example, a resistor with bands of yellow, violet, red and gold will have first digit 4 (yellow), second digit 7 (violet), followed by 2 (red) zeros: 4,700 ohms. Gold signifies that the tolerance is ±5%, so the real resistance could lie anywhere between 4,465 and 4,935 ohms.

Resistors manufactured for military use may also include a fifth band which indicates component failure rate (reliability); refer to MIL-HDBK-199 for further details.

All coded components will have at least two value bands and a multiplier; other bands are optional.

The standard color code per EN 60062:2005 is as follows:

Black = 0, Brown = 1, Red = 2, Orange = 3, Yellow = 4, Green = 5, Blue = 6, Violet = 7, Gray = 8, White = 9

Therfore if the puzzle mentions resistance and the puzzle is Orange / Green + Brown / Black your answer would be 3 / 5 + 1 / 0 or 160.

NOW FOR YOUR PUZZLE:

You will be using the just described resistance color code above to figure out this puzzle. Also you will need to figure out the colors of some birds, all birds mentioned are birds of North America..

So here we go.  The final is at N42 27.ABC  and W082 59.DEF where 

A= Cardinal + Female Cardinal + Wilson's Warbler

B = Indigo Bunting + Baltimore Oriole

C = American Gold Finch + Summer Tanager + Creeper

D = Partridge - Wilon's Warbler

E = Martin

F = Tanager + Cardinal + Crow
