How to change the size and/or color of intersection points in Illustrator?

Question

Is there any way to make these blue dots smaller or lighter? Its not anchor point. They are intersections between grid lines...

Checked the preference but don't know where to look or what to change.

Answer 1

These must be anchor points, or you wouldn't see them. You can change the colour of selection lines and dots in the Layers palette:

1. Open the Layers palette: Window > Layers or f7;
2. Select your current layer, most probably 'Layer 1' in the palette—if it isn't already;
3. Click the 'Palette options' button on the top right of the palette: an icon that looks like an downwards arrow and four horizontal strokes;
4. In the flyout that appears, click Options for "Layer 1"...;
5. Choose a new 'Color' for the layer. You can choose a set of preselected colours from the pull-down, or click the square to the right to create your own desired colour with your OS's colour picker.
6. Click OK.

Under Preferences > Selection & Anchor Display you can select from a few options how to display anchors. There should be an option that reduces your anchors' size a little there, the leftmost option.
