Modifying and creating colour schemes
If you've tried various colour schemes but haven't found one that's quite right,
you can modify any of the colours in an existing scheme and update the
scheme, or create your own separately named scheme based on the existing
scheme.
To modify a colour scheme:
1. Click the Colour Scheme button on the default context toolbar (or choose
Tools>Scheme Manager...) to display the Scheme Manager.
2. Pick a colour scheme from the list on which to base your new scheme,
and jump to the Edit tab at the top of the same dialog.
3. On the Edit tab, each of the five scheme colour numbers (plus the
Hyperlink, Followed Hyperlink, Active Hyperlink and background Page
colour) has its own drop-down list, showing available colours in the
WebPlus palette.
4. To set or change a scheme colour or adjunct colour, simply click the
adjacent button and select a new colour. Click More Colours... to display
the Colour Selector.
5. To store the modified scheme in the Schemes Manager, click Save
Scheme.... Leave the name unaltered to overwrite the existing scheme.
6. To apply the scheme to the current web site, click OK.
To create a new scheme, you can follow the above procedure but, at Step 4,
enter a new scheme name instead of overwriting the existing scheme.
Setting transparency
Transparency effects are great for highlights, shading and shadows, and
simulating "rendered" realism. They can make the critical difference between
flat-looking illustrations and images with depth and snap.
Transparency may seem a bit tricky because by definition, you can't "see" it
the way you can see a colour fill applied to an object. In fact, it's there all the
time in WebPlus. Each new object has a transparency property: the default just
happens to be "None"—that is, no transparency (opaque).
Transparencies work rather like fills that use "disappearing ink" instead of
colour. The more transparency in a particular spot, the more "disappearing"
takes place there, and the more the object(s) underneath show through. Just as
a gradient fill can vary from light to dark, a transparency can vary from more
to less, i.e. from clear to opaque, as in the illustration:
