Blue is the colour I see most often outside. It is how I feel when I can't see it. The sky over Alberta is clear most days, a beautiful azure. We get an inordinate amount of sunlight, one reason why homes can be run on solar panels, greenhouses are lucrative, and we all have red necks. Almost every day I can look out and see blue from horizon to horizon, interrupted only by the occasional fluffy white cloud. It's a blessing.
I suffer from Seasonal Affective Disorder (SAD), so when we have a week of grey, wet, dreary weather, it hits me hard. I don't feel like getting out of bed. I have no desire to do anything. It seems nothing can make me happy. It strikes in the winter when although there is still a brilliant blue sky, it's only there for a few hours a day.
