-#define TB_WHITE   0x08
-# The default color varies, but usually it makes the background black and the foreground white.
-# You can also combine these colors with the following style attributes using bitwise OR:
-#define TB_BOLD      0x0100
-#define TB_UNDERLINE 0x0200
-#define TB_REVERSE   0x0400

-#define TB_HI_BLACK  0x2000
-#define TB_BRIGHT    0x4000
-#define TB_DIM       0x8000
-# For example, to set the foreground color to red and bold, you would do 0x02 | 0x0100 = 0x0102.
-# Note that you must pre-calculate the value because Ly doesn't parse bitwise OR operations in its config.
-#
-# Moreover, to set the VT color palette, you are encouraged to use another tool such as
-# mkinitcpio-colors (https://github.com/evanpurkhiser/mkinitcpio-colors). Note that the color palette defined with
-# mkinitcpio-colors takes 16 colors (0-15), only values 0-8 are valid with Ly and these values do not correspond
-# exactly. For instance, in defining palettes with mkinitcpio-colors, the order is black, dark red, dark green, brown, dark
-# blue, dark purple, dark cyan, light gray, dark gray, bright red, bright green, yellow, bright blue, bright purple, bright
-# cyan, and white, indexed in that order 0 through 15. For example, the color defined for white (indexed at 15 in the mkinitcpio
-# config) will be used by Ly for fg = 0x0008.
+# Ly supports 24-bit true color with styling, which means each color is a 32-bit value.
+# The format is 0xSSRRGGBB, where SS is the styling, RR is red, GG is green, and BB is blue.
+# Here are the possible styling options:
+#define TB_BOLD      0x01000000
+#define TB_UNDERLINE 0x02000000
+#define TB_REVERSE   0x04000000

+#define TB_DIM       0x80000000
+# Programmatically, you'd apply them using the bitwise OR operator (|), but because Ly's
