It's a beige or almond color. About 3/4 on each side. Looks like the 'Capitol 800 Series', but the flat side doesn't have the bend or lip at the end.

See our 55-017, 55-023, or 55-029. Look over the end profile dimensions of each glazing bead and see if one of these might work for you. If you want, you could order a sample of each from our Samples Page here.
