Solid colours
Applying a fill is easy, whether you’re selecting a custom colour from the Colour
tab or a preset colour from a whole range of colour swatches in the Swatch tab.
The Colour tab can operate in
several modes available from a
drop-down menu—HSL Colour
Wheel (shown), HSL Colour Box,
HSL Sliders, RGB Sliders, CMYK
Sliders and Tinting. We’ll
concentrate on the HSL Colour
Wheel which is very popular
amongst drawing professionals.
The HSL Colour Wheel is made up of four key components—the line/fill
swatches, the outer Hue wheel, Saturation/Lightness triangle, and an Opacity
slider.
The Line/Fill swatches govern whether the selected colour is applied as a line
colour, solid fill, or both simultaneously.
The small circles shown in the wheel and triangle indicate the current setting for
hue and saturation/lightness, respectively. Drag either circle around to adjust the
overall HSL value.
A Tinting option in the Colour tab’s drop-down menu (not shown above)
allows a percentage of shade/tint to be applied to your colour.
