Setting the layer color  

Each layer in a drawing is assigned a color. progeCAD uses the BYLAYER color as the default color setting for entity creation so that new entities are drawn in the color of the layer on which they are inserted (set in the Drawing Settings dialog box).    

Using the Explorer, you can set or change the color assigned to a layer. With the direct-editing feature, you can click on the color you want to change, and then select a new color from the dialog box that appears. Changing a layers color automatically changes the color of all entities on that layer with the BYLAYER color.

To change the layer color

   1   Do one of the following to choose Explore Layers ():     

    On the ribbon, choose Home > Explore Layers (in Layers) or choose Tools > Layers (in Explorer).

    On the menu, choose Format > Explore Layers or choose Tools > Explorer > Explore Layers.

    On the Explorer toolbar, click the Explore Layers tool.

    Type explayers and then press Enter.

   2   Click in the Color column for the layer you want to change.

   3   In the Color dialog box, select a color on one of the following tabs:

    Index Color Click BYBLOCK, BYLAYER, or one of the 255 index colors. You can also type the color number in the Index box.

    True Color Click a basic color, click a color in the color palette, enter the Hue, Saturation, and Luminance (HSL) values, or enter the Red, Green, Blue (RGB) values. There are more than 16 million true colors from which you can choose.

    Color Books Select a color book from the list, then click a color. You can select Show Only Color Book Colors Used in Drawing to limit the selection to only those color book colors that are used in the current drawing. If necessary, create or edit color books by clicking Color Book Editor. For more details, see Using color books.

   4   Click OK.

Entities dont have to use the layers color.
You can assign a specific color to an entity, which overrides the layers color setting. When you create a new entity, use the Format > Colors > Select Color command to change the current color. For an existing entity, select the entity, right-click for the shortcut menu, and choose Properties to change the entitys color using the Properties pane.
