main window does not use Bespin theme (menu background is white (255 255 255) Scrollbar, toolbar, etc — are also too bright) — it also relies on Windows® classic color scheme, but I want editor & other plugins to follow neither Coder plugin settings, nor AkelPad.ini:Options.Colors value, but current
system color (.theme), I had to customize AkelEdit' colors to make it look like my current Windows classic color scheme:

(in this image, HexSel background = 48 48 48, but main Editor background = 44 44 44, HexSel text color = 142 89 36, but editor text color = 77 147 112) — there is no checkbox "Windows Default" or a dropdown list with a "COLOR_*" constants {"Window Text", "Button Face", "Hilight", "Highlight Text", "Hot Trackikng Color", etc.}
HexSel.dll and Explorer.dll even didn't import "GetSysColor" function from user32.dll and
use Windows® color scheme, but Coder
did static import and does not set system colors on editor (+ each "language" syntax), Explorer, HexSel, SpecialChar, etc, that's why I find Coder plugin HARMFUL and even useless (it does not determine a language of pasted text to a new file without its name extension)! P.S. Coder plugin is updated today, but I find it impossible to test all themes: this plugin is always broken for me for years, and even when Highlight is enabled, it does not applied (Explorer, HexSel or other plugins use system colors instead of Coder or AkelEdit), maybe it depends on "High contrast" mode, or something else (turning off "Ignore colors specified on webpages" is also ineffective, but keeping it on gets me rid of "hard-coded" white background inside .CHM files)…
