Ren'Py Change "what" and "who" colors

[PlayWithMe]

Hey, I am having a bit of trouble with this, so what I want to do is allow the user to customize the color of the text and name. That should be done on the Preferences screen, so each (important) character will have 6 bars, 3 for what and 3 for who. being Red, Green, and Blue first I tried to do it with persistent:

init -4 python:
    if persistent.color_ed_whatR is None:
        persistent.color_ed_whatR = 255
    if persistent.color_ed_whatG is None:
        persistent.color_ed_whatG = 0
    if persistent.color_ed_whatB is None:
        persistent.color_ed_whatB = 255
      
    if persistent.color_ed_whoR is None:
        persistent.color_ed_whoR = 0
    if persistent.color_ed_whoG is None:
        persistent.color_ed_whoG = 0
    if persistent.color_ed_whoB is None:
        persistent.color_ed_whoB = 0
  
init -3 python:
    #What ?
    if persistent.color_ed_what is None:
        persistent.color_ed_what = (persistent.color_ed_whatR, persistent.color_ed_whatG, persistent.color_ed_whatB, 255)
    #who
    if persistent.color_ed_who is None:
        persistent.color_ed_who = (persistent.color_ed_whoR, persistent.color_ed_whoG, persistent.color_ed_whoB, 255)

then on the screen:

bar value VariableValue(persistent.color_ed_whatR, 255):
    xalign 1.0 yalign 0.0
    xmaximum 400
    ymaximum 15
    left_bar Frame("left_bar", 10, 0)
    right_bar Frame("right_bar", 10, 0)
    left_gutter 0
    right_gutter 0
    thumb "thumb_bar"

I'm sorry, but an uncaught exception occurred.

[...]
  File "renpy/common/00barvalues.rpy", line 277, in get_adjustment
    value = getattr(self.object, self.field)
TypeError: getattr(): attribute name must be string

Well, the error say it all, and a look at

confirm what the error message said :

variable
    A string giving the name of the variable to adjust.

You need to pass the name of the variable to VariableValue, not directly its value.

Thanks.
Then I ask something, then I see the answer I fell much stupid. Anyways

  File "game/script/in_game_screens.rpy", line 460, in execute
    bar value VariableValue("persistent.color_ed_whatR", 255):
  File "D:\Programas\Renpy 7.3.2\renpy-7.3.2-sdk\renpy\sl2\sldisplayables.py", line 242, in sl2bar
    return renpy.display.behavior.Bar(range, value, width, height, vertical=False, **properties)
  File "D:\Programas\Renpy 7.3.2\renpy-7.3.2-sdk\renpy\display\behavior.py", line 1619, in __init__
    adjustment = value.get_adjustment()
  File "renpy/common/00barvalues.rpy", line 277, in get_adjustment
    value = getattr(self.object, self.field)
AttributeError: 'StoreModule' object has no attribute 'persistent.color_ed_whatR'

Do I have to do something else to use persistent files?
As I said if I alter on the initial declaration, then delete persistent files changes the color during the game.

My bad, I followed what you already wrote, without taking care of the fact that you worked with a persistent value. VariableValue is for literal variable, while you're working with an attribute of the persistent object. What you need to use is

Thanks, I will try, I tried also without persistent and didn't give an error but then I quit the game and reopen it goes back to the initial value. I don't know if I will use that but how it works? (I mean save a value outside of a save in non-persistent), In practice what would be the difference?

And since I am where already to do something like what is on the attachments (change between the tabs on the right is, in each button call a different screen right? (just yes or no, I want to try to do it myself).

And for last I don't want to go back then I click on the right button on the mouse, because I use the "return" button to change something, can I cancel it and/or do something the I click it

1st the screen that show every character:

The screen that shows the info then I click on the character. What happaned has then I go for page 2 for the 1 character and then clicked on the RMB and tried go to the second and it has only one image it brokes. The 3 first line don't let that happen but if as like 3 images it starts at the second, and if I put it always as 0 it does go back and forth.
