Color displays are available for $5-7, although they are usually only 2-4" diagonally with up to 240x320 pixels at 16-18 bits of color per pixel.
But it definitely did open up a flood gate of opportunity. You see ILI9341 and ST7735 TFT displays all over the place, even if they're a little too small for large pieces of equipment.
Not to mention the explosion in cheap individually-addressable color LEDs and drone-driven advances in small DC motors. It's fantastic, you can pretty much just plug electronics together like Lego bricks at this point.
