Some pictures I made with my Spectrum over 10 years ago

A couple of notes about Spectrum graphics:

• The resolution of the screen is 256x192 pixels. Period.
• There are 8 colors available, with a brightness bit. In practice you have 15 colors in total (because bright black and non-bright black are identical, which is actually a very good thing because it allows you a lot more freedom with images with black background). The colors are fixed (ie. no palette system of any kind).
• Pixels are binary. That is, a pixel is either on (ie. the 'foreground color') or off (the 'background color').
• Color information is separate, and it defines the color of each 8x8 pixels block. The color information specifies the foreground color, background color and brightness (it also has a bit for flashing the 8x8 square, but that's seldom useful for anything).
• This means that for each 8x8 square on screen you can only have two colors, period. Also either both must be bright, or neither one.
