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!)
Set up costs are normally included with any home improvement job, painting separate times for complete exterior painting can essentially cost double, unless agreed before work begins in painting quote.
First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size.
THE BACKROUND. Collect information on the artist and the historical background. To analyze "Guernica" by Picasso, you need to know that Guernica is a town demolished by the Nazi, and you have to read up on the essential features of cubism. To interpret the image of kissing people covered by a piece of cloth in Magritt's "The Lovers", whatever you guess by looking at the painting falls flat once you know that the artist's mother got drowned in the river, and when found, a piece of cloth was wrapped around her head. So, don't rely on your skills and taste too much, there are things you need to KNOW before you start making assumptions. The historical background of the paintings itself is important. Was the artist an innovator, did he start a new trend or movement, whose steps did he/she follow? What experiments was he involved with? How was the painting perceived by the contemporaries? Claude Monet started impressionism with the painting "Sunrise. Impressions". Malevych started suprematism as a development on abstractionism, laying out the new artistic theory of the color, the form and the composition of the painting. The rough lines and raw colors in the fauvist paintings may be traced back to Van Gogh. Do you think there is something new suggested in the painting you are looking at, or is there anything at all distinguishing about it?
Main thing to consider when considering painting exterior of your home is; How long do I plan living in this house. If your answer is any longer than 1 year, you may reconsider from painting trim only to painting exterior completely. From a quick glance, fresh trim paint will work from an aesthetic point of view, but not even close from complete protection and value points. Therefore, being fugal painting, does not always mean painting just enough to get by, sometimes costing much more in the long run.
* To design a look with analogous colors, you can have any three colors next to each other on the color wheel. Successfully combining these colors in a room is one of the easiest, next to using monochromatic colors. In general you will want your design to use similar tones throughout the room except in the case of accent colors, which may be bolder.
Another satisfactory whitewash can be made by diluting a moderately heavy cold lime paste (about 33 lbs. of hydrated lime and 8 gallons of water) with 5 gallons of skim-milk.
