 		 #176588 - A Color Sequence
Responding to: ???'s previous message
Chico:
I have attached a spreadsheet that shows the 125 colors in the order of counting 0-4 for each color using Blue as the low order 0-4 digit, Green as the middle 0-4 digit and Red as the most significant 0-4 digit. Whis was done in an Excel 2007 version spreadsheet and saved as a .XLSM type file. It uses an embedded VBA Macro. Note that if you open in an earlier version of Excel the colorizing off the cells in the color table may not work or may display the wrong colors.

Click Here to Open the spreadsheet

Note that some browser accesses may change this .XLSM file to a .ZIP format. In that case please download it and save to your desktop. Then change the name back to .XLSM so that it will open with Excel 2007.

                     you can - wth a caveat            01/01/70 00:00      
   Can I ask a color question?            01/01/70 00:00      
      Start a new thread            01/01/70 00:00      
         Interpolate in RGB or HSV but not in your tabulated index.            01/01/70 00:00

      If you answer a question...            01/01/70 00:00      
         Just tests, no MOSFETs yet...            01/01/70 00:00      
            The ULN2803 will ruin your colors!            01/01/70 00:00      
               when doing color            01/01/70 00:00      
               miss the point... the point is the color generation...            01/01/70 00:00      
                  Help with what?            01/01/70 00:00      
                  already answered            01/01/70 00:00      
                  Have you seen my link?            01/01/70 00:00      
                     Yes, but dont helps...            01/01/70 00:00      
                        as usual            01/01/70 00:00      
                           not "SPECIFIC, SPECIFIC, SPECIFIC"            01/01/70 00:00      
                              Use another look-up table...            01/01/70 00:00      
                                 Thats it!            01/01/70 00:00      
                                    Copy from a professional solution...            01/01/70 00:00      
                                       Youtube has some nice videos...            01/01/70 00:00      
                              you've got it wrong and what are you doing            01/01/70 00:00      
                                 I care Erik!            01/01/70 00:00      
                                    why are you "going through steps"?            01/01/70 00:00      
                                       Kai videos?            01/01/70 00:00

                                                Now I'm confused            01/01/70 00:00      
                                                   Still never telling what you do want            01/01/70 00:00      
                                                      you are going for an intensity ratio ...            01/01/70 00:00      
                                                      I see no contradiction...            01/01/70 00:00      
                                                         I think it was incrementing of the index that was the proble            01/01/70 00:00      
                                                            Chico, are you getting it            01/01/70 00:00      
                                                               Words            01/01/70 00:00      
                                                                  He should have enough information now...            01/01/70 00:00      
                                                                     that is often the problem ...            01/01/70 00:00      
                                                                        Words fail me...            01/01/70 00:00      
                                                                  How to add            01/01/70 00:00      
                                                                     You don't have paletted device so stop thinking about index            01/01/70 00:00      
                                                                        only 125 colors            01/01/70 00:00      
                                                                           Smooth? Sudden? This make no sense!            01/01/70 00:00      
                                                                              I'm tired from guessing, Chico...            01/01/70 00:00      
                                                                           So you haven't read what we have posted?            01/01/70 00:00      
                                                         Thats it Kai...            01/01/70 00:00      
                                                            place my 125 unchangeable colors in a nice sequence in this            01/01/70 00:00      
                                                               Lacks words for me!            01/01/70 00:00      
                                                                  You need more levels.            01/01/70 00:00      
                                                                  See previous suggestions!            01/01/70 00:00      
                                                            only 32 words            01/01/70 00:00      
                                                            what is "nice sequence"? and for what purpose?            01/01/70 00:00

                                                                           my thought is            01/01/70 00:00      
                                                                              Did I get you?            01/01/70 00:00

                                                                                          right, you compensate for this by ...            01/01/70 00:00
