Colour Specbox

  Click on the Colour Option to enter

Item: Clear HBLs
Type: Action Bar
Desc: Erases the whole of the memory
bank containing any HBLs which may have
been set up since Canvas was loaded. Be
careful when working around this option
as there is no Undo function for the
HBL list. See the HBL section of this
manual for more details.
Opts: All HBL and palette options on
the Colour Specbox (COS)

Item: Default All
Type: Action Bar
Desc: Resets all 16 colours in the
current palette to the colours they
were when Canvas was loaded. Careful -
you cannot Undo this function!
Opts: All options on the Colour Specbox
(COS), Colour Bar (MM)

Item: Default One
Type: Action Bar
Desc: Similar to Default All (described
above), except that it only defaults
the current colour selected on the
Colour Bar at the bottom of the Main
Menu screen.
Opts: All options on the Colour Specbox
(COS), Colour Bar (MM)

Item: Palette
Type: Infobar
Desc: Select from here which one of the
64 palettes (0 to 63) you wish to use.
Opts: All options on the Colour Specbox
(COS), Colour Bar (MM)

Item: R.G.B.
Type: Special Selector
Desc: By clicking on the three sliders,
you can alter the Red, Green and Blue
values of the current colour selected
on the Colour Bar at the bottom of the
Main Menu screen. You need not drag the
sliders to the position you wish, (like
the Control Panel DeskTop Accessory
requires) - simply click at the
appropriate position on the Slider bar.
R.G.B. levels go from 0 to 15. On an
Atari STE (the enhanced computer), all
15 levels are active. On an ordinary ST
only 7 seven levels are available - the
levels go up in steps of 2 : 0 and 1 are
the darkest, 2 and 3 the next darkest,
and so on up to 14 and 15.
Opts: All options on the Colour Specbox
(COS), Colour Bar (MM)

Item: Set HBL
Type: Action Bar
Desc: Allows you to set where an HBL
containing the palette (selected on the
Palette Infobar above) should occur on
the screen. Note that this enters the
current work screen. In the top left
the Y value of the line you are at is
displayed. Move the line to your chosen
place and click the left mouse button.
This enters that HBL in the HBL table.
The right button aborts the option. You
will then be returned to the Main Menu.
See the HBL section of this manual.
Opts: All options on the Colour Specbox
(COS)

Item: Shift Pal
Type: Action Bar
Desc: By clicking on the box marked
'Shift Pal', all of the colours between
the Rotate markers (on the Colour Bar -
bottom of Main Menu), will be 'shifted'
towards the current colour selected
(again on the Colour Bar). This means
that each of the Red, Green and Blue
levels of these colours are brought
towards the values of the current one.
To shift just the Red, Green or Blue
levels of those colours, click on the
R,G or B buttons below this option.
NOTE: If you use an Atari STE, this
function will shift the RGB levels by
2 places, not 1 : this is to maintain
compatability between the machines.
Opts: All options on the Colour Specbox

Item: View HBLs
Type: Action Bar
Desc: By clicking on this button you
may view all the HBLs set so far.
Before you do so though, ensure that
you select the palette that is to be at
the top of the work screen using the
Palette Infobar above. Press any key to
return to the Main Menu. Refer to the
HBL section of the manual.
