Is there anything wrong with the below, in a GC app?

[colour set];
// Do drawing

Are there special rules or gotchas with local statics like 'colour'
above? Is 'colour' always safe to use where I try to send it the
'set'
message? Could it be already-collected/lack strong references to keep
it alive?
That pattern has always worked for me in 10.5. The static variable is
a strong reference.
