To quote from chapter 2: Fire on the Mountain... 'Ralph spoke first, crimson in the face.' The reason why Ralph blushed was because he'd just realised that, after spending a great deal of effort organising the building of a huge fire, he had no means to light the fire. Ralph blushed from a combination of embarrassment and from the shame of having to publicly admit that he didn't have any way of lighting the fire.
Ralph is blushing because he is embarrassed or ashamed. The phrase "crimson in the face" suggests that his face has turned red from blushing.
Ralph Keyes - author - was born in 1945.
