Bright daylight usually measures between 5,000 and 6,000 K. Cool-white fluorescent bulbs measure between 4,000 and 4,600 K. Moonlight measures between 4,100 and 4,150 K. Color halogen and daylight bulbs measure between 3,200 and 3,500 K. Incandescent bulbs measure between 2,700 and 3,300 K. Low-pressure sodium bulbs measure 2,000 K. The flame of a candle measures 1,850 K. In general, the measure from warm to cool breaks down as follows: It’s known as the Kelvin rating, and the lower the number, the warmer the illumination. As these bulbs gradually replace the incandescent variety, manufacturers are making every attempt to appease the public by providing them in a wide range of color temperatures.Ī more scientific approach relies upon a system of measurement to evaluate the relative warmth or coolness of different sources of light. On the other hand, the effects produced by compact fluorescent lighting can vary widely. Full-spectrum bulbs are the closest possible to neutral. White fluorescent lighting is extremely cool. Daylight bulbs emit a cool, bright light to mimic the great outdoors. Incandescent light imparts a warm yellowish tint. Every light source has its own particular ambiance. That’s why the beige that was perfect when chosen at the paint store can turn almost pink on your living room wall.įluorescent light is not the only culprit. Since fluorescent lighting tilts toward the bluer end of the spectrum, it can cause particular problems with the reds. Some colors are more sensitive to the effects of these frequencies than are others, and these are the ones most likely to fall victim to metamerism. The fact is that every different light source contains its own distinctive combination of color frequencies. Although fluorescent light causes few problem in most cases, it’s a different story where color is concerned, For one thing, it provides a good general illumination, and for another, the practice has a more benevolent effect on the company’s bottom line. Paint stores, particularly the big-box variety, generally prefer to light their environment with fluorescence, and there are good reasons for that. Either the paint store has made a terrible mistake, or the color has changed inside the can. Despite the number of hours spent in front of the paint display, the color finally chosen is almost certain to be quite different by the time it reaches the buyer’s home. The type and quality of that light can appear to change any color vastly from what you may have thought it was before. Without light, color simply doesn’t exist. Anyone who has tried to distinguish red from blue in the dark of night soon finds that it’s impossible. That’s because what appears to be a certain hue is nothing more than reflected light. What’s happening is metamerism, and it can affect any color at any time, day or night, indoors or out. In fact, these changes take place on a regular basis, but what’s really going on? They are not really changes they are shifts in color preception.Surprisingly, it may not be your eyes, and the fix might require nothing more than a change of light bulbs. The result looked, well, terrific to my eye.When beige looks pink, blue appears green and The Sherwin Williams Alabaster looks more yellow than white, it’s not necessarily cause for concern. PS - the talented model builder who goes by the name "Bone" (based in NW near Seattle I think), recently did a bunch of test bodies using the Testors Color Shift paint over other color basecoats, including bright red IIRC. And at least for me, ring my trial, the enamel based Color Shift paint also largely shared the favorable lacquer-like characteristics. Very sadįortunately today we have both Testors and Tamiya spray paints that work far better than the current formulations of spray enamels. I suspect that the EPA regulations among other factors, have caused the decline. I noticed the differences in the Gloss Black enamel spray paint starting around the early-mid 1990's, and it has gotten worse from there. This is a shame as the original 1960's/1970's Testors Gloss Black spray was fabulous - nearly foolproof, no orange peel, quick to dry, and terrific glossiness. Sags, uneven coverage, slow to dry, et al. What I was much less satisfied with was the current formula of Testors Gloss Black enamel which you are to use as a basecoat for the Color Shift paint. I was very pleased with the outcome - almost no orange peel, excellent gloss, went on perfectly with two light coats. I just painted an NHRA style "competition coupe" body with the new Testors color shift paint.
