Алгоритм окраски выбора
Метод Gdb кажется лучше, но можно сделать это с strace, также:
файл
-e write=set
Perform a full hexadecimal and ASCII dump of all the
data written to file descriptors listed in the spec-
ified set. For example, to see all output activity
on file descriptors 3 and 5 use -e write=3,5. Note
that this is independent from the normal tracing of
the write(2) system call which is controlled by the
option -e trace=write.
strace-p-e write=1-s 1024-o Это распечатывает несколько больше потребности thanyou (шестнадцатеричная часть), но Вы можете sed это легко.

Может быть, негативный эффект:
псевдо:
int red = originalColor.red
int green = originalColor.green
int blue = originalColor.blue
int newRed = 255 - red
int newGreen = 255 - green
int newBlue = 255 - blue
Color negativeColor = new Color(newRed, newGreen, newBlue)
Или добавление синего цветового эффекта:
int red = originalColor.red
int green = originalColor.green
int blue = originalColor.blue
int newRed = 255 - red
int newGreen = 255 - green
int newBlue = 255 - blue + 100
if newBlue > 255 {
newBlue = 255
newRed = newRed - 50
newGreen = newGreen - 50
if newRed < 0 {newRed = 0}
if newGreen < 0 {newGreen = 0}
}
Color negativeColor = new Color(newRed, newGreen, newBlue)
If you're using HSB, try shifting the hue by half the maximum value either up or down, that should give you the "opposite" color (also called the complementary color). However, this doesn't do you any good for the grey spectrum, which has no hue and will thus look identical.
If you do this with both hue and brightness, you will get a kind of "negative", which works in all cases. A true negative would have you "flip" the brightness value around the mid-point, but that doesn't work for medium-gray, which would still be medium-gray.
It not always possible to make a color brighter (what do you do with white?), so shifting both hue and brightness by half is the most reliable if you're looking for contrast.

One technique you can use is to swap the item's foreground (text) color and its background color. If the text and background colors of your item already have a pleasing contrast, the selected item should continue to look good.

That is the technique used on this site (Stack Overflow) when you mouse-over the tags in your post. They turn from DarkBlue-on-LightBlue to LightBlue-on-DarkBlue. Try it to see the effect.
