iLiad's 16 Colours [updated]

A table is printed in iRex's How-to-make-content-Guide, which lists the 16 colours of our iLiad. But they are not shown there, just pure listing, so I did this: a overview of iLiad's colours.
Have a look at the png file on your iLiad.

OK: All files got an update.
colours.zip includes htm, gif, bmp, & png files.

Q:
# I don't know why iLiad shows for example a horizontal bar with brighter colour in cell #CCCCCC in 01.htm [01.jpg].
# The left side of screen looks brighter in real & on photo .

to-do-list:
# text in 16 different colours
# dithering of non-native colours

Have a look at the png file on your iLiad.

to-do-list:
# photo [file on iLiad's screen]
# html version
# pdf version
# text in 16 different colours
# dithering of non-native colours

Thanks for taking the time to make the file yokos! As soon as i get home ill check how well the iliad displays the 16 colors

Since the PNG file doesn't follow the specifications, would it be of any value
to check it on the iliad? It doesn't use native colours, except for black.

Black is (RGB 0,0,0,), but white is not (255,255,255), only (248,248,248).
The darkest grey is said to be (17,17,17), but the PNG image has (16,16,16),
and there are similar offset problems all the way up to white.

EIther the original image was not produced with the intention of being a
test card, or there has been some PNG optimization that altered the
colours.

Any solution to this?

I think the problem with PNGs are, that they embed gamma, so depending on the device you look at those PNGs (Mac, Windows, iLiad, ...) the colors/greyshades are a bit shifted, for a more detailed description see: Gamma Problem in PNGs.

So PNGs a bit "over-engineered" and not very well suited for these kind of things, as the colors are a bit different on each platform...

So the best would be to either use gifs (and make sure, that the drawing application does not alter the color information) or simply use a PDF

I'm sorry, I didn't get it right.
So something got wrong in converting to png. I don't use png very often, just for screenshots. I never thought that some problems could emerge.
I don't keep the source & output files [last week I did bmp, too] with me right now, so you will get a correct version tomorrow.

Thanks kusmi for the link, crux is hidden in detail.

[Edit]: I updated the files, read 1st post.
