I gaze at the sky, wondering at primary blue.  Why so dark?  Is the sky not a good enough measure?  Does that deep, purplish hue better represent the title?  Yes, the sky is full of golden light, and sometimes swings towards green.  But then there are times when the clouds are out in their full glory, radiant with golden sunlight and silver dew unshed.  In those moments, the sky is a deeper periwinkle rather than turquoise.  Perhaps it would be a better measure to say--primarily--strawberries are red, the sun is yellow, and the sky will be our blue.
