I painted light gray that now looks lavender on the wall...I am pretty sure it is the lighting in the room (CFL bulbs) as when I take the roller into another room with natural light or fluorescent lighting...


I painted for many years. And now work with photoshop each day.
The selected grey was probably in the blue family instead of yellow family. Most interior colors look better if they come from the warm yellow family, including greys.
There are greys for every color in the spectrum ... from yellow to red to blue. If you pick a grey with bit of red, it will start to look mauve. Orange and it will look brown. Blues inside the grey will turn purple real quick.
Moreover, all colors and finishes are contextual and pick up surrounding colors. Especially satin-or-shiny finishes, because they pick up local colors that change intended hue. For example blue drapes will turn white room bluish. If the house next door is red, and the light comes in window, it will turn white room into pink. Green leaves, and the light from window turn white room green. So when you pick a grey that has bit of blue, the color can change for many reasons beside light bulb. Each room is totally different.
Most folks pick colors by looking at color chip in the store, instead of painting a section of wall inside home. And most folks do not ask the paint store clerk which tints are in that particular color. Sometimes the black tint will turn some bases into a bluish hue.
Go back to paint store and get another grey color from the yellow spectrum.

Contrast really dark but seems to improve after the tv has been on several hours


Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Panasonic TC-P42U1 plasma. Lost it's vivid colors basic color is black and white and green and blue if tint color tone etc. Is turned up. However a blue ray video plays with full color. Could it be a lose...


I have an old Toshiba TV and was going to replace it with a new plasma because it has suddenly (the week of July 19, 2010) lost color. It has only green and blue tint. Changing the "tint" on the menu didn't help. The color comes and goes relative to nothing that I can measure, such as how long it is turned on, etc. Reading other complaints from owners of Plasmas, I am thinking it is cable related. I have Charter Cable. Playing a DVD, I have to readjust the tint back to normal. Hope this info gives clues.

My tv sceen has a stain that makes anything white look yellow.


The color image is comprised of three colors, Red, Green, and Blue.
All the other colors are mixtures of those colors. The yellow picture indicates that your set is lacking sufficient blue drive.

First of all check to make sure that the tint control is not misadjusted.
The next thing is dependent upon the age of your television. If it's an older set that yellow tint is a sign of an aging picture tube.
If it's a newer set, less than 5 years old, have it analyzed by a electronics technician that is familiar with televisions if he is skilled enough he will know right away if it's the picture tube or not.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
