Some topics of a more technical nature for you to consider.

Here's a compendium of some more-technical topics that don't really fit under FAQ's. These mini-tutorials will help you get a bit more background on some topics like color, monitors and digital images. These are brief, so you should do your own further research! As always, if you need more information about our services, contact us.
What is color, anyway?  Color is simply our perception of the wavelength of visible light. We call a particular light wavelength of about 650 nanometers by the name "red", while a computer monitor calls red "#ff0000".

Color is also called "Hue", and can be pure, or mixed with any shade of gray. The purity of a particular hue is called "Saturation". Finally, as we move the grayscale component value from black toward white, we change the "Value" of the color from low to high.
How does monitor color work?  In the computer's digital world, colors fit a coordinate system called Red-Green-Blue, or "RGB" for short. Our "#ff0000" above for "red" was like writing "#max-red-no-green-no-blue", since the two "f"s re­pre­sent the maximum possible red value of 255 in hex­a­de­ci­mal number notation (whatever that is.) The two "00" pairs correspondingly ordered up zero green and then zero blue. Monitors use R, G and B filters to display color as a mixture of these three fun­da­men­tal colors, mixing the light that comes out of each mon­i­tor "pixel", or picture element, which are all too small to see in normal use. Green, then, in your monitor is ordered up by the code "#00ff00", and blue is #0000ff".
How does the color picker work?  Perfect Paint Preview's cus­tom-designed color picker comes up when you click one of the zone color buttons above your image. The tool shows every avail­able col­or a monitor can display. It provides easy access to all 1,530 available monitor hues, at every sat­u­ra­tion and value point. You can select a color graphically with the mouse or specify it numerically. Informa­tion on the left and right will introduce you to this outstanding tool.
How do digital cameras work?  Digital cameras work something like monitors in reverse. Where monitors shine white light through R, G and B filters to display colors, digital cameras use R, G and B filters to block light of the wrong col­or and detect reds, greens and blues in the scene they're photographing. These filters cover microscopic light-sen­si­tive regions called "pixels" (just like the monitor) arranged in a row-and-column array, which then record the intensity of light of the filtered color.

A little electronic-circuit-based math, and the camera con­structs a digital "map" of the scene's hue, saturation and value, which becomes a digital image file. That's what happens "under the hood" when you take your photo to upload to the Perfect Paint Pre­view™ tool.
What's to know about digital camera image files?  First, these image files have a length and width, and these two dimensions have lots of consequences. For our purposes in the Perfect Paint Preview™ service, you want a picture that is at least about 4000 pixels wide and about 2200 pixels high. That's about what you get from a "10-megapixel" cam­era. Smaller images don't have the detail you will want.

The second thing to know is that your camera probably saves your image as a ".jpg" ("Jay-peg") file. That's a very good format to use, with this caveat. If you do any work with your image before you submit it for your preview, make sure you always save it with a "100" quality factor. Normally software will default to 90 or even less.
How does paint get its color in the real world?  While monitors and digital cam­eras work by full light control using colored filters, paint works very dif­fer­ent­ly: it receives en­vi­ron­men­tal light and re­flects its own color back to your eye. This means that paint's appearance, including to a small degree its color, is de­pen­dent on its environment: on wea­ther, time of day and so forth. So always remember that paint must be eval­u­a­ted recognizing its dependence on those un­con­trol­led factors.
