What is "yellow"? A color with high red and green components:
yellow_redThreshold = 200;
yellow_greenThreshold = 200;
yellowMask = (redBand > yellow_redThreshold) & ...
(greenBand > yellow_greenThreshold);
Perhaps you want a low blue component also?
...
yellow_blueTreshold = 100;
yellowMask = (blueBand < yellow_blueTreshold) & ...
(redBand > yellow_redThreshold) & ...
(greenBand > yellow_greenThreshold);
I'd prefer the HSV color space to determine a color.
