APPLE COLOR BUGS
|
||
----------------
|
||
|
||
COLOR LINES (NOT SOLIDS) ON COLOR BACKGROUNDS OFTEN PRODUCE STRANGE
|
||
EFFECTS DUE TO APPLE'S COLOR-GRAPHICS HARDWARE. RESULTS DEPEND ON
|
||
WHICH COLORS YOU ARE ARE USING...
|
||
|
||
GREEN-ORANGE OR VIOLET-BLUE COMBINATIONS WILL MAINTAIN TRUE COLORS,
|
||
BUT LINES WILL BE THICK AND STAIR-STEPPED. OTHER COMBINATIONS WILL
|
||
PRODUCE A MIXTURE OF COLORS.
|
||
|
||
FOR MOST APPLE GRAPHIC APPLICATIONS, BLACK IS THE BEST BACKGROUND
|
||
"COLOR".
|
||
|
||
RELOCATING COLOR SECTIONS WILL PRODUCE INACCURATE COLORS IF YOU MOVE
|
||
OTHER THAN 14 PLOTS LEFT OR RIGHT (ARROW KEYS). MOVING SEVEN PLOTS
|
||
LEFT OR RIGHT WILL PRODUCE COMPLEMENTARY COLORS!
|
||
|
||
