Anything relating to non Sinclair computers from the 1980's, 90's or even before.

Well, I only had a good RGB capable TV in the late 2000s. I doubt many people used anything other than RF.
So my comments are about regular RF connections on late 1980's TV.

Here's a capture from real hardware (at 1:25). Don't know if it's RF or composite video, but it's PAL signal:

Colours are still bright and saturated, but little differences have appeared.
For example, on the boat Yellow is about #E3E300; on the sky Cyan is #52FFFF, etc.

My point is that both systems looked good back in the day.
They took advantage of existing tech, and the user would optimize the TV settings to get the best picture. :D

So what? Almost none of the soviet TVs did have RGB input either. People were needed to add it themselves or to call a service technician.

this looks too good to be RF, but too bad for RGB i remember (and since the title says +3/+2A maybe a composite mod?)

as i said, very limited and rough "optimizations"
just can't get some color combos to become more readable without breaking the other ones

Hi

My computers during the 8 bit golden age were a speccy clone, - the Timex TC2048 and the C64.

I find so silly the wars between the difference scenes, specially these days. I love all retro computers and now I own not only those two I mentioned above but others too.

Regarding the Commodore colours as an amateur artist I think the palette was very well thought out, it works very well in general but it wouldn't have hurt to an optional palette with some full saturated colours!I think the colodore palette is the closest to the real thing and as someone else has mentioned we always could intensify or mute the colours according to our taste using the TV or CRT monitor settings. Regarding the 320x200 hires mode, it was not that much used it is true but it not only had higher resolution than the Speccy but also regarding the attributes it was a bit more advanced as it allowed any of the 16 colours as ink or paper (perhaps this was mentioned before but I didn't read all of the thread yet).

I like coding games for retro computers and one of my latest projects is Patolas' Adventures #1 and on the C64 it is looking like this:

And I just love how it looks, this video capture was taken from an emulator using the colodore palette. What do you think?

I also have been working on two mock ups one for the Speccy 48k :

and the other for the Timex Hicolour mode:

I love how the game looks on the 3 computers, each one has its strengths.

Please take a look at the NIRVANA+ Engine. In a standard Speccy 48K, instead of this:

you will be able to have something like this:

That was a fun read. Why didn't cartridges use the 320X200 mode? It seems like a real waste of hi resolution. I am allergic to the C64's BASIC but I think the games on it are really good, and many times better than our Speccys but maybe not as original in design.

Lots of games use the high resolution character modes (because you can mix and match high and low res characters on the same screen). The bitmap modes, in general, are better suited to static screens and by and large the low Res modes with more colours give a better result (or one of the funky screen modes caused by fiddling registers on the fly much like multicolour Speccy graphics).
