Is this a Speckled Wood?

Observation - Is this a Speckled Wood?. Description: I've checked various websites to confirm identification and they seem to agree that this is a Speckled Wood. However, my Collins Butterfly Guide shows this butterfly to be a much redder colour rather than brown. Is the book wrong?
