Will the Amiga do true colors?????

[iowtheme]

Hi All

On my A4000 I am running the Classic Workbench OS3.5 in DBLNTSC: High Res No Flicke at 256 Colors.

I have Pics on my desktop and it is Bocky will the Amiga do true colors.

Thank

Not without a graphics card, no.

You can give Ham Wb a shot. Not true colour , but lots more colours. http://aminet.net/util/wb/hamwb.lha

the ham modes on the amiga were made for static images...specially to show pictures
if you use a ham mode on workbench or anything with movement you will get some kind of gfx corruption

AGA is true colour - 24 bit. Just because you are limited to 256 or fewer distinct ones at one time does not mean that the ones you have aren't true.

What about a monochrome screen mode, with blue and red color. Is that true color aswell?

AGA has a pallet range of 24bit, alas only 256 colours in a palet.

HAM8 is 24 bit I believe

AFAIR AGA can be considered a truecolor system because it has a 24-bit palette.

Is sometimes Truecolor used (incorrectly?) to describe what is actually Directcolor? (Is that even the right term?) Screens which have no CLUT (i.e. any colour on any pixel) which AGA cannot do.

always thought 256 colours was 8 bit, well for the pc anyway.

[meega]

Amiga 256 colours is 8 bit-planes, each colour can be chosen freely within the entire 24-bit range (8 each for red, green, and blue).

These days, true colour is at least 24-bit for all pixels, no restrictions. 24-bit has always been the least resolution to qualify as true, as the average person can distinguish about 220 different shades of each of R, G, or B. So 7 bits for a component isn't enough.

And 8bit != true color. Period.

[meega]

8 bits of red, and 8 bits of green, and 8 bits of blue, all at the same time, for a given colour. True.

Set up an entire screen all of one colour. Now change one bit, and only one bit (the least significant one), in one component. Only a true colour display will show the difference. AGA can do that.

Show me how I can have more than 256 colors on screen then w/o any tricks if normal AGA mode is true color. That each color component has 8 bit still doesn't make it true color since the maximum number of colors is 2^8 = 256. Not exactly true color, is it? Or why do I have to use shade tables and shit if I want to "fake" more colors? Tell me.

[Toni Wilen]

Nobody called SVGA or newer 256 color paletted modes true color either. (original VGA only had 18 bit palette).

True color = any 24bit (8bits/color component) pixel possible anywhere.

Exactly.

In ham 8 the base palette is 24 bit but the modifier is limited to the most significant 6 bits for each RGB component. Ham8 isn't a true colour mode. True colour to me means any pixel can have any value (15, 16 or 24 bit).
Changing one pixel in ham can corrupt everything after until a base colour is selected.

Maybe so, but this problem is readily apparent nonetheless:

How can the AGA chipset achieve 24bit quality, when the video dac is only 18 bits (6 bits per beam, U30 in the A1200 schematics, chip labeled BT101)?

[Supamax]

True color (24 bit) = 8 bits/256 shades per Red/Green/Blue component.

A true color 640x480 screen has 307.200 pixels: the maximum on-screen colors is 307.200, but it doesn't mean it's not true color.
A true color 800x600 screen has 480.000 pixels: the maximum on-screen colors is 480.000, but it doesn't mean it's not true color.
And so on..
