Almost my fave in the compo. Nice composition, very stylish.

Cool, I like this.
Please note, the palette isn't OCS, so it will look slightly differently on OCS.

Thanks a lot, I appreciate the feedback!

@bifat what exactly did you check? The iff files come directly from DPaintIV which can not do AGA. Then the png versions are conversions from those iff files using imagemagick convert to have a web compatible format. So the color values in png *should* be the closest matches of the original OCS colors in 8bit-per-channel RGB.

Ah I think I know what happened. I got tricked by 32 year-old software :)

Not necessarily a problem of the old software. All tools in the conversion chain need to know that for example color $37f becomes $3377ff, not $3070f0. IFF ILBM actually saves its palettes in 24bit since ever.

OK, I need to put more work into that next time. Thanks!

Thanks for asking!
It's only a problem when a pic leaves OCS and gets converted to PNG for getting handed in a compo.
There's no problem when an OCS pic stays on OCS, even with old tools which did something stupid with the lower nibbles per RGB. The ILBM format did everything right, but even EA's own paint program shows all sorts of strange behaviour.
There are different kinds of issues - some tools do stupid things. Some people restrict themselves to 16 or 32 colors and think that makes a pic OCS.
Simply take care that the upper and lower nibbles per RGB are the same for every color in the palette. Or you can load the pic into grafx2, right-click on "PAL" and adjust the slider "RGB Scale" to 16. This will produce the right colors, but it may truncate your palette and formerly super smooth gradients may become a bit more blocky.
