Expand a selection to include areas with similar color

Do one of the following:

Choose Select > Grow to include all adjacent pixels falling within the tolerance range specified in the Magic Wand options.
Choose Select > Similar to include pixels throughout the image, not just adjacent ones, falling within the tolerance range.
To increase the selection in increments, choose either command more than once.

Note: You cannot use the Grow and Similar commands on Bitmap mode images or 32‑bits-per-channel images.
