Is there a RegEdit to Change Task Bar Title Bar, Start Menu colors

V 2004 (OS 1941.508)
Good morning there a RegEdit to Change Task Bar, Start Menu colors and also the Active Title Bar and Inactive title Bar colors that works, please?
I have searched and tried numerous ways to set my Taskbar and Start Menu to one color and the Activated Title bar and nonactive title Bars to another nothing I have searched for works because the Task and Start Menu Checkbox won't activate its greyed out If I do the "Dark mode" scenario I have a permanent Black screen and no matter what with Dark mode both checkboxes default to the same color after I set them Eg Green Green not eg Green Green and pink pink NOT Green and Pink and the inactive Titlebar a different color to the active Title bar
I have just had a Win 10 Update, will installing the May 2020 upgrade before doing a Clean Install fix it?

TIA Regards Dasha

Dasha,

Active titlebar colour is set in HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM

For example,
{deep green}

Code:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM]
"AccentColor"=dword:ff3e8910
;decimal 4282288400

{pale green}

Code:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM]
"AccentColor"=dword:0000cf7c
;decimal 53116

I found the colour codes by playing around in Settings, Personalisation, Colours and readng off the resultant codes in that Registry key.
- When you change the Registry values, the colour change takes effect but the colour shown as selected in Settings, Personalisation, Colours does not change.
- No restarting is needed, the change is immediate.

I have not played around with any of the others but some are identified in
