From Andrey Smirnoff To All 15 March 1998


Hello, All !

Please tell me the composition of the spectrum palette, in RGB components:
for example:
black: R:0, G:0, B:0... etc. for the 256-color VGA mode.
You can use soap.

Sincerely, Andrey Smirnoff.

About the 256-color VGA I won’t tell you, but the palette for 24 bit please:

│ Normal │ Bright
─────────┼─────────────┼─────────────
Black │ 0,0,0 │ 0,0,0 <- this is not an error, this is a system function ;)
Blue │ 0,0,153 │ 0,0,170
Red │ 153,0,0 │ 187,0,0
Magenta │ 153,0,153 │ 204,0,204
Green │ 0,153,0 │ 0,204,0
Cyan │ 0,153,153 │ 0,221,221
Yellow │ 153,153,0 │ 238,238,0
White │ 153,153,153 │ 255,255,255

My emulator uses the values 00h,2Ah,3Fh (Black,Normal,Bright).

0 1 2 3 4 5 6 7 8 9 A B C D E F 0 1 2
R 0 0 1 1 0 0 1 1 0 0 2 2 0 0 2 2

From Pavel Fedin To All 17 March 1998


Hello, Andrey Smirnoff! I remember, on March 15, 98 you took it and launched
in All with this:

AS> Please tell me the composition of the spectrum palette, in RGB components:
AS> for example:
AS> black: R:0, G:0, B:0... etc. for the 256-color VGA mode.

Elementary. You take the Spectrum color number and arrange it into bits.
The bits will be the components R, G, B. If the bit is 0, then
the corresponding component is 0. If 1, then either say 127, if BRIGHT
for it is 0, or 255 if BRIGHT=1.

Bye, with a pack of vishezes, Pavel Fedin.

Why is your brightness increasing so gradually on Bright,
this is not Gray Scale. And it turns out that blue is almost no different
bright from not bright, but white is significant.

No, 127 is too dark, it is better to take about 2/3 or even
more.

I don’t believe it! At least my eyes say that the palette in my emulator
is very similar to what I saw at 32WTC.

From Roman Petrov To All 30 March 1998

By the way, my eyes tell me that Bright 0 on your emulator
looks a little dark compared to Specky.

Vladimir is that you?
...why did you tell Pavel Fedin about the palette?

VY> more.

in short, hot Estonian guys :))) here’s a palette made from emulsion.

RGB form

Norm Bright

In principle, you can make adjustments for any eyes.
