“A beautiful, rare day in May” is the first stage direction in The Color of Heat, by Saul Zachary, the first of two spring-themed stories for Readers Theatre Repertory’s final production of the season. “A beautiful day in May” is the direction that begins A Betrothal, by Lanford Wilson, which completes the show. Bob Martin directs.

“This is such a seductive time of year,” says Martin of his reasons for picking the plays. “One moment it’s still winter, and the next, the promise of a glorious Portland summer.” Martin says the season’s vagaries reminded him of these stories. “These two tales, with their bitter and their sweet, feel perfect for the Pacific Northwest at this time of year.”

The cast includes Sarah Lucht and Christine Shields, Curtis Hanson and Jeff Gorham.
