Posted at 2021-10-13 by HughB Black, White, Red, Green, Blue, Cyan, Yellow, Magenta This is what we used to use in the late 1970s when those first computers first came out. Posted at 2021-10-14 by Robin Wed 2021.10.13
Try believing monochrome lime green phosphor!! The first consumer PC 1978 I used pre-dated the Comodore 64 and Timex Sinclair by four years and I built as a kit: The Heathkit H89
I paid over $1500 USA dollars which was a third of a years salary (electronics tech) then. With Yes Fragile and Rush Fly By Night albums playing still took six weekends to build, along with parts to wire wrap the additional 16K board (to save the $150 for a new board) so that I had the maximum amount, 64K!! It had an amazing single color lime green phosphor 80 char output. Yeah I was top kid on the block back then!! I still have it, fired it up a could of years ago and was amazed at the blazing speed of 6 minutes just to boot off the 100K hard sectored 5 1/4 floppies. Incidentally, NASA has offered me ~$1000 just for both the Z80 and 8080 processors inside as they are much needed for repair stock and no longer manufactured. I challenge your 1970's claim @hughb as that would have had to have been early / mid 80's ;-) Commodore 64 Date introduced: August 1982 . . . and I thought I was dating myself! Posted at 2021-10-14 by @gfwilliams So yes, 3 bit = 8 colors However there's dithering built in, so if you don't require solid color it's actually pretty flexible. try the emulator: https://www.espruino.com/ide/?emulator&upload&gist=203fe0c3768b5df1b09b0769bf7d2c4c Attachments: Posted at 2021-10-14 by HughB @robin - you did have it bad. Posted at 2021-10-14 by Andrewmk ZX Spectrum colours! Attachments: Posted at 2021-10-15 by HughB I forgot Sinclair ZX80 was monochrome. https://en.wikipedia.org/wiki/ZX80?wprov=sfla1 Posted at 2021-12-06 by cottjr Thanks everybody for this thread. I was wondering why the Bangle 2 display looked funky, with less vivid colors than the original Bangle. Anyhow - I've been totally blown away with how good the battery life is. No doubt the 3-bit display and lower resolution helps battery life quite a bit. Posted at 2021-12-06 by HughB This code is quite magic - trying to figure it out.
If I wanted a whole screen of a mix blue and cyan - how could I do that ? Posted at 2021-12-07 by @gfwilliams
The first argument of Posted at 2022-11-30 by rchateauneu I would like to have saturated colors on my Bangle2, without dithering. According to List of monochrome and RGB color formats: 3 bits, there should be eight possibilities: (255,0,0) => 100 (pure red, no dithering) Posted at 2022-11-30 by @gfwilliams Yes, that's correct - these correspond to |

While waiting for the watch and preparing one or two small apps, I was thinking what it does mean that the LCD has 8 colors? While designing graphics, what colors can I expect?
