VGA Attribute Enable Blink in graphics modes?

[superfury]

What happens when the VGA Attribute Controller Mode Control's Blink Enable bit is set during graphics modes? Will blinking be applied (color/black) at all? What happens in this case? What happens in 1(MDA), 2(CGA/4 colors), 4(16 color) or 8 bit(256 color) modes when this bit is set on?

BLINK - Blink Enable
"When this bit is set to 0, the most-significant bit of the attribute selects the background intensity (allows 16 colors for background). When set to 1, this bit enables blinking."
