Fortunately, you can always get your primer tinted for free. Getting your primer colored the same as your paint will save you a coat of paint. Of course, I always recommend doing a minimum of 2 coats of paint so that your finish sheen looks consistent.
Red is the color of fire, it instills joy, strength and confidence in people. In some languages red is a synonym of beauty and wealth. But we shouldn't forget that it is also the most aggressive color - if there is too much of this color, it irritates and wears you out. On the other hand small accents of red in the interior cheer you up and put you into a good mood. If red is the predominant color in your interior, it sets you into active and determined mode.
What are the major color fields in the painting and their role in the entire composition? Is the light optically realistic or expressive as in Matisse's painting?
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.
Are the contours rough or concealed?

If red is the color of fire and yellow is the color of sun, then orange color, which originates from the blend of these two colors, combines both warmth and light in it. Light muted orange accent will give your interior cosiness and warmth, especially in the room with windows facing north. Bright orange color in the interior on the other hand is more of a claim for originality.
