LightGreen¶

Status: Experimental

present and registered, but lightly documented and not yet covered by dedicated tests.

Description¶

LightGreen

The named colour RGBColor[0.88, 1, 0.88].

Examples (3)¶

Every input below was run against the current Mathilda build and its output recorded.

Applications (3)¶

A pale pastel -- its own constant, not a tint of Green

In[1]:= LightGreen
Out[1]= RGBColor[0.88, 1, 0.88]

An OwnValue, not an inert head -- already resolved

In[2]:= FullForm[LightGreen]
Out[2]= RGBColor[0.88, 1, 0.88]

Usable wherever a directive is expected

In[3]:= Head[Graphics[{LightGreen, Disk[]}]]
Out[3]= Graphics

Implementation notes¶

Definition. LightGreen is one of Mathilda's named colour constants, bound as an OwnValue: register_color("LightGreen", rgb_color(0.88, 1, 0.88)) in graphics_init (src/graphics/graphics_init.c) makes the bare symbol evaluate to the literal RGBColor[0.88, 1, 0.88] and marks it Protected. The docstring is kept centrally in src/info.c.

Representation. LightGreen evaluates to RGBColor[0.88, 1, 0.88], so FullForm[LightGreen] is RGBColor[0.88, 1, 0.88] and Head[LightGreen] is RGBColor. The exact 1 green component prints as an integer while the 0.88 reds print as reals (color_component). It is a separate constant from Green, one of the pale Light* pastel family.

Usage & limits. As a resolved colour literal it is accepted anywhere a directive is — Graphics[{LightGreen, Disk[]}], PlotStyle -> LightGreen, a light ArrayPlot cell. It carries no opacity; use Opacity[a] or the four-argument RGBColor for translucency.

Attributes: Protected.

Notes & additional examples¶

Notes¶

LightGreen is the named colour RGBColor[0.88, 1, 0.88]. It is bound as a Protected OwnValue, so it resolves to a real colour literal wherever a bare argument is evaluated: FullForm[LightGreen] is RGBColor[0.88, 1, 0.88] and Head[LightGreen] is RGBColor.

The exact 1 green component prints as an integer while the 0.88 reds print as reals. It is a separate constant from Green, one of the pale Light* pastel family. It carries no opacity; use Opacity[a] or the four-argument RGBColor[r, g, b, a].
