Colors

[bradc]

Hi Folks!

 

Is there a link that describes the 9/11 "bug"?

 

The example above works great for me but I was wondering if you have to use PMGs to draw the color bands?  Can it be done another way?

 

Thanks!

Here's my short program to display all 256 colors at once on the Atari. Since right now I can't connect my real Atari, I'd love for people to use this on real Ataris and do screen captureS (NTSC, PAL, and SECAM), then post the screen captures.

 

 

10 REM * DISPLAY ALL 256 COLORS
11 GRAPHICS 9:FOR V=0 TO 15:COLOR V
12 FOR N=0 TO 4:PLOT 5*V+N,0
13 DRAWTO 5*V+N,191:NEXT N:NEXT V
14 D=256*PEEK(561)+PEEK(560)
15 FOR N=1 TO 16:READ V:POKE D+V,143
16 NEXT N:FOR N=0 TO 25:READ V
17 POKE 1664+N,V:NEXT N:POKE 512,139

I am glad I found this.

I ran Atari Control Picture on my French 130XE machine and made a photo with SECAM colors palette.

I'm aware of poor quality of this picture, but maybe somebody find it useful.

Atari was connected by standard video output to LCD TV/Monitor LG Flatron M1917A and photo was made with Sony Xperia XA1 model G3121.

Interesting - I don't think I've seen Atari's SECAM output before.

 

It looks like it has better saturation than other standards.

Do you have a PAL machine you can try with a similar setup?

In attachment is the same picture displayed by standard monitor output of Atari 65XE in PAL. The same monitor settings: sharpness: 100, brightness 60, contrast 60, colour 60. The same smartphone was used.

Unfortunatelly I haven't got NTSC computer yet, but I'm going to fix this in the near future.

I was experimenting with this myself recently, I would like to contribute. All 3 pictures were taken on the same multisystem SONY Trinitron CRT.

 

▼ Atari 130XE NTSC

▼ Atari 800XL NTSC

▼ Atari 65XE PAL

This looks interesting especially with the colors on the Atari 130XE. It seems that the hues repeat starting row "B", I have never seen that before! By the way, what program are you using?

[Krystone]

The program is Atari Control Picture. Enclosed.

Thanks for the program. I got a chance to take a look at the colors of my Atari 800.

Here the cooler colors are well represented. However unlike what I usually see online and on emulators the last row is not brown or orange, it's green.

However, I'm not sure if this is entirely incorrect, despite what the bar on the right suggests (It's hard to see, but instead of RGB it's orange, blue, and purple).

Apologies for the poor image quality, but I took a screenshot of Pac-Man. Here one of the ghost is cyan (Inky) like the arcade. However, most screenshots online (and even the packaging that I have), the ghost is green.

Compared to most screenshots of Moon Patrol that I have seen for the Atari 8-bit Home Computers, including the box and even the commercial, the colors are very different, the mountains are green instead of yellow and your buggy is magenta instead of blue. If anything the colors perfectly match those from the arcade which makes me wonder if many of the programmers at Atari had their computer's colors calibrated like this. Most of the games that I have look fine with the exception of Frogger and Popeye (from Parker Bros) where the blues are somewhat purple and Pole Position where the grass is an artificial blue-green color and your car wrecks into a orange and green explosion instead of yellow.

I was once told... NTSC stands for Never The Same Color...
