Custom color chart

The built-in color names are usefull for a web designer as they are the official 'html' color names.
However , you may different needs.

- A color blind people may only need to know if something is close to red, green , blue or white. And many intermediary color names may be confusing.

- If you are a painter , you may want to use official color palettes , or internal color names from your company.

- You may just want to see the colors in your own locale ( Thai , Japanese , .. ) which are not supported by default

Let's write a simple example.

To define a chart , edit a text file. Give it a name that ends with .csv.
Say we define 'colormap.csv'

The file structure is simple. Its a list of rows , where each rows has 2 cells. The first cell is the color name , and the second cell gives the color RGB components.


The text file has to be UTF-8 format. The default Microsoft windows format is different but will work if you are not using special characters.
UTF-8 is required for proper French , and non latin chartset. You can find converters on the web.

Lets define 4 colors. The color picker will then match the closest of those 4 colors when it want to display a color name.

Its red!,#FF0000
So green!,#00FF00
Blue,#0000FF
White,#FFFFFF

For instance , row 0 states that #FF0000 ( that is red=FF ( hexadecimal )  , green = 0 , blue = 0 )

When done , write this file on your phone Sd Card. Open the color picker and get to the configuration screen ,using the button menu.

   

Click the circled arrow to choose the color map on the Sd Card directory.




Exit the color picker , restart it. Now it uses your color scheme!

                   

The closest color from this pink variant is red , so it writes 'its red!' which is defined in our .csv file.

To revert to the default color map , erase the file name in the text field ( empty string with 0 characters )



Note:

Common color schemes in printing industry are RAL and Pantone ( PMS ). Those scheme are not bundled in the application as their respective companies
claim intellectual property right for the color list.
