Blue is the color of calmness and peace. It draws in and intoxicates. The strength of this color is as a rule underestimated. It creates precondition for deep reflection about life, calls to find the meaning and truth, it calls for not sensual but rather spiritual impressions.
Yellow color is sunny and light. Historically this color symbolizes gold and wealth, and in the East it is a symbol of eternity and greatness. This color creates optimistic and bright mood and goes together greatly with the other colors of the interior. At the same time the warm sunny tints never carry a negative charge. Yellow color creates an impression of lightness and joy. It frees you from the weight of worries, problems, and limits. This color is hope and expectation of big happiness in its multiple forms starting with sex and going up to some philosophical and religious outlooks.
You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better.
Repainting your house is a tricky business. Some rely on painting companies to do the job for you. Hiring the house painting service may also cost you. But if you are planning to paint it yourself, you might want to consider the basics; and consider the time and effort you will put on painting your house.
Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
Feel free to email me if you have questions at the email addresses below. But most important, you'll find that with each painting you'll get better and better. Carry forward everything you learn from each work and eventually you'll have real talent! But only if you keep at it. And don't worry about people telling you you're crazy. They told that to van Gogh too! Sweet justice Vincent, sweet justice. He's certainly getting the last laugh, isn't he? And the world will know who Vincent van Gogh was for the rest of time. Not a bad gig.
We are living in a highly pressurised and competitive world. There are more people chasing fewer jobs and in order to compete and survive in this world our children need to be as highly educated as possible. This has led parents to pressurise play-schools and nursery schools to begin teaching children reading, writing and arithmetic in the hope that they will be better prepared for formal schooling when they enter grade 1.
