The result is actually a crimson large, which would appear a lot more orange than crimson. At some point, the crimson large turns into unstable and starts pulsating, periodically increasing and ejecting a few of its atmosphere. Ultimately, all of its outer layers blow away, creating an growing cloud of dust and fuel termed a planetary nebula.
