 In the RGB (red/green/blue) HTML color realm, the number
 "17" (as I have long known through my own heuristic math
 delvings, but which I did not fully appreciate until today via
 learning about the uses for the number "16" from the Colorado
 State Engineering site) is key.  The #FFFFFF I placed above
 is the hexadecimal (HEX) code for the color "white" (the top
 cock, as in the adult male domestic chicken) which has the
 equivalent RGB code of 255,255,255.  There are sixteen (16) 
 basic color gradations, if black (#000000) is allowed.  They are
 "F" / "E" / "D" / "C" / "B" / "A" / "9" / "8" / "7" / "6" / "5" / "4" /
 "3" / "2" / "1" / "0"  -  This means that A = 10, B = 11, C = 12,
 D = 13, E = 14, and F = 15.  However, "0" is in termpostion
 (tpo) "1", and therefore "F" is in tpo "16".  This is significant 
 when dealing with color combinations.  "17" is this system's
 rung number.  0/17 = 0.  0 + 17 = 17 and 17/17 = 1, and 1 =
 #111111 in HEX and 017,017,017 in RGB.  Black is black
 and white is white, but every color between these in which the
 six HEX alpha/numeric characters are alike are variants of gray.
 So 000 (0), 017 (17), 034 (34), 051 (51), 068 (68), 085 (85),
 102, 119, 136, 153, 170, 197, 204, 221, 236, and 255 are the
 central sixteen RGB numbers.  16 x 16 = 256.  From this set
 far more colors than are needed can be generated.  One color
 in the w3c core sixteen is silver (#C0C0C0 or 192,192,192).
 What is "C" in HEX is "204" in RGB.  If 204 is divided by 17,
 12 remains.  It happens that 204 - 12 = 192, and C is 12 as
 17 shows.  [ It is 12:55 PM and I am taking a break. ]
 -
 The other w3c colorsare: white, black, one gray (#808080 or 
 128,128.128), red(#FF0000 or 255,0,0), yellow (#FFFF00
 or 255,255,0), blue (#0000FF or 0,0,255), aqua (#00FFFF
 or 0,255,255), lime(#00FF00 or 0,255,0), fuchsia (#FF00FF
 or 255,0,255, navy (#000080 or 0,0,128), maroon (#800000
 or 128,0,0), teal (#008080 or 0,128,128), olive (#808000 or
 128,128,0), green (#008000 or 0,128,0), & purple (#800080
 or 128,0,128).  There are nastinesses herein whose sources I
 am not aware of and whose consequent results I am not able
 to dispute, but I am bringing them to the fore.  I have been an
 AOL member since April 18, 2000; and almost from the first I
 was puzzled by the color system, especially by the color now
 (and possibly then) known as either cyan or aqua.  Still, green
 then was what lime now is, and I'm fairly sure purple then was
 what fuchsia now is.  In light of the aqua/cyan color, these new
 namings seem apt, and I do find no fault with fuchsia, purple,
 or lime; but the color which is labeled green is going to take 
 some getting used to.  What is at stake, if it is at stake, is
 the prism-derived notion of what a primary, secondary, and
 so on color is.

 On to "16" and what I culled from the engineering site.  This
 involves remainders resulting from divisions by "16" and--as
 with "17"--"0" is included.  In this regard, MS Explorer will
 sometimes change the RGB code I have put in.  Reminder:
 16 divides into 256 (not 255) 16 times.  Because divisions
 by 16 extend to four places, .0000 must be used for black.
 1/16 = .0625, 2/16 = .1250, 3/16 = .1875, 4/16 = .2500,
 5/16 = .3125, 6/16 = .3750, 7/16 = .4375, 8/16 = .5000,
 9/16 = .5625, 10/16 = .6250, 11/16 = .6875, 12/16 = .7500,
 13/16 = .8125, 14/16 = .8750, and 15/16 = .9375 and F = 15
 and 15 x 17 = 255.  Why is knowing this valuable?  Here is
 the link to 
 
                      Engineering Colorado State HTML color support
 Read it only/ as its reason for being is to aid the students there.
 On this page is an explanation of how to convert an RGB 
 value to its hexadecimal equivalent.

 The catalyst behind this entry was and yet is my desire to know
 color names for the 216 HTML safe colors.  My immediate ? is:
 What is the name of the #00CCCC HEX color?
 [ 7:17 PM  -  I've decided to make up my own color names. ]
 -
 [ 21MAY07: There will be more to come here. ]
   -
   One pleasant light event was that finally I did find what I'd long 
   been vigorously seeking, but I have chosen not to use it; yet, 
 since the information there is worth pondering:
   *** this e-whip to it ***.
   -
   Also this from the University of
   Rhode Island.

 two other worthwhile sites to visit:
 
 color names at Learning Web Design

 RGB HTML at Keller

 [ 22MAY07: Have been thinking about "green" and/ after concluding
    that midway between 255,0,0 and 0,0,255 is 0,128,0// I went to 
    the Internet Options color area.  I chose to test my conclusion via
    the 204,204,204 bg color I am using.  It changed the bg color but
    because I did not OK the initial OK it moved to the basic colors
    palette IE7 uses.  Suddenly (though it now seems I should have 
    known this) I realized/ the colors palette at AOL Journals is the same
    one, but AOL Journals does not use strict RGB codes.  It uses the
    associated codes w3c uses.  As I now know which of the palette's
    colors is 0,128,0/ I am next going to see how it is coded in AOL J. 
    -
    It is, of course (as I half-suspected): 008000.  Besides, all this is
    already noted above where I presented the core w3c 16 colors  
    along with both codes.  ]

 [  26MAY07:  This morning I found a site where the names given
                     to certain RGB (rgb) colors are more to my liking.

    Also this morning (with Google's help) I re-learned that with 
    paints and dyes the primary colors are red,blue,yellow.  Try
    a "primary colors rgb" search. ]
