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!)
Remember, you will need to clean the airless in that same fashion before you return the airless back to the rental company.
Airless Tip: If you have somebody who can start masking off the trim, have them start on that while you convert the airless to a new color. When changing colors with an airless paint sprayer it is a good idea to have a second bucket filled half way with clean water. Place the intake hose in the clean water gently without getting the old color everywhere in the water. Take the tip out of the airless and spray all of the old paint out of the hose and back into its original paint bucket. Be careful when doing this that you recognize when the paint starts turning watery. When it does point the gun into the first bucket and spray until it looks pretty clean. It doesn't need to be perfectly clean. When it looks good, clean off the intake line in the clean bucket and get the old color off the intake line. Now place the intake line inside of your new trim paint.
TEMPERATURE OF COLOR. Colors have temperature, referred to as warm or cool. In painting, reds, yellows and oranges are referred to as warm colors and blues, violets and greens are referred to as cool colors. One of the biggest lessons you will ever learn about color temperature though, is that the appearance of color can change drastically depending on its surroundings. For instance, a certain yellow would appear much hotter if it were surrounded by a violet then say an orange. Another important lesson in color temperature: Warm colors will advance in a painting and cool colors recede.
Types of Paint. Water-based paints are usually referred to as emulsions and were traditionally used only for interior walls and ceilings. But recently tremendous advances in paint technology mean that water-based formulas, especially the high-performing acrylics, are available for all surfaces, from woodwork to metal, and for interior and exterior use. The advantages of these paints over oil-based ones is that they are cleaner, have less odour and are more environmentally sound. Brushes can be rinsed clean with water.
If new caulk is applied, main body portion needs to be touched up, and most of the time new paint will not match aged paint even using exactly the same paint out of the same paint can, as sheen difference will come into play.
