Colour bars/Display is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
The task is to display a series of color bars across the width of the display. The color bars should either use the system palette, or the sequence of colors: Black, Red, Green, Blue, Magenta, Cyan, Yellow, White.

<lang basic>10 REM The ZX Spectrum display is 32 columns wide, so we have 8 columns of 4 spaces 20 FOR r=0 TO 20: REM There are 21 rows 30 FOR c=0 TO 7: REM We use the native colour sequence here 40 PRINT " ";: REM four spaces, the semicolon prevents newline 50 NEXT c 60 REM at this point the cursor has wrapped, so we don't need a newline 70 NEXT r</lang>
