You can use color to help you group objects visually. You can assign the color of an object either by layer or by specifying its color explicitly, independent of layer. Assigning colors by layer makes it easy to identify each layer within your drawing. Assigning colors explicitly provides additional distinctions between objects on the same layer. Color is also used as a way to indicate lineweight for color-dependent plotting.
ACI Colors
ACI colors are the standard colors used in AutoCAD LT. Each color is identified by an ACI number, an integer from 1 through 255. Standard color names are available only for colors 1 to 7. The colors are assigned as follows: 1 Red, 2 Yellow, 3 Green, 4 Cyan, 5 Blue, 6 Magenta, 7 White/Black.
All objects are created using the current color, which is displayed in the Color control on the Properties toolbar. You can also set the current color with the Color control or the Select Color dialog box.
If the current color is set to BYLAYER, objects are created with the color assigned to the current layer. If you do not want the current color to be the color assigned to the current layer, you can specify a different color.
If the current color is set to BYBLOCK, objects are created using color 7 (white or black) until the objects are grouped into a block. When the block is inserted into the drawing, it acquires the current color setting.
To set an ACI color for all new objects
On the Properties toolbar, click the Color control.
Click a color to draw all new objects in that color, or click Select Color to display the Select Color dialog box and do one of the following:
On the Index Color tab, click a color or enter the color name or number in the Color box.
On the Index Color tab, click BYLAYER to draw new objects in the color assigned to the current layer.
On the Index Color tab, click BYBLOCK to draw new objects in the current color until they are grouped into a block. When the block is inserted into the drawing, the objects in the block acquire the current color setting.
Click OK.
The Color control displays the current color.
