My screen colors are corrupted such that blues are green, reds are electric blue, yellows are lavender-pink. Pictures taken since this happened are OK when transferred to PMB/other picture program. Do not remember any trauma to camera, but it had misbehaved a few times before by staying white for some time or showing flashing lines across image.

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.

You might have "color filter" settings. Turn the digital filters off. Here is what manual at p72 says. "You can take pictures using digital filters. The filters consist of color filters such as red, blue and green, a soft filter that produces a fuzzy effect. Color filters Eight colors, black-and-white, sepia, red, pink, violet, blue, green and yellow, are provided for the color filters. When you select a color filter in the Digital Filter mode, the display on the LCD monitor is filtered with the selected color, and the pictures are taken in that color."
