Frequently Asked Questions

Color Wheels

How are the colors of the artists' paints determined?
In almost all cases, paint colors are taken directly from manufacturers online color charts. In the future there will be an ongoing effort to correct any instances of colors not being accurately replicated in Colorist for Artists. In this regard, your participation in A Better Match would be gratefully appreciated.
I thought the visual color complement of red was green. Why does your color wheel say cyan?
The true visual color complement of red is cyan. Partly because there was little scientific knowledge of color when the first color wheel was developed, and partly because mixing complements were not properly distinguished from visual complements, misinformation about color complements arose and persists to this day. For more information, see Color Complements and After-Images.
Why are two color wheel (visual and mixing)?
The visual color wheel is the color wheel to use when selecting colors that are visually harmonious, such as complements, triads and tetrads. The mixing color wheel has the limited function of selecting a color's complement to mix with that color to reduce its chroma. As the chroma is reduced, the original color will move towards grey, its colorfulllness having being reduced. If the lightness of the color and its complement differ significantly, then the mixed color will change in both chroma and lightness.
How was the visual color wheel derived?
The visual color wheel is an adaptation of the CIECAM02 Color Appearance Model, the most uptodate scientific color model appropriate to this purpose.
How was the mixingl color wheel developed?
The mixing color wheel has been derived emperically from data available online and in literature. Because color mixing is so complex, there can be no general rule or formula that specifies how hue, chroma and lightness change as one color is added to another. However there is considerable experiential evidence as to which two colors, when combined in the right proportions, will produce a true grey.


What about future updates to Colorist for Artists?
Once you purchase a license for Colorist, all future updates are free, for the lifetime of the product.
How does licensing of Colorist for Artists work?
The demo can be freely downloaded and has no time limitations. However, all artists' paint color names are masked, being replaced with "xxxxx". Once a license is purchased, and the registration key has been entered into Colorist, the proper color names will be displayed immediately. The demo version thus becomes fully enabled; there is no need to download or install a second application.
How do I purchase a license for Colorist for Artists?
All license purchases are handled by ShareIt Inc., a leader in secure online transactions. Simply click on the appropriate link on the Order Page. to initiate this process. ShareIt payment options include credit card, Paypal and wire transfer. Once your online transaction is complete, ShareIt will send you an email that includes the registration key. This key must be copied and then pasted into Colorist for Artists.
What is the difference between a Personal and Corporate license?
A Personal license is solely for non-commercial purposes. A single Personal license may be used on 2 PCs in one household. The Personal license will be assigned to the individual's name. A Corporate license is required for commercial use. With a Corporate license the organization can use the program in a business, academic, or government environment.
How do I register Colorist, once I have received my registration key?
Firstly, highlight and copy the entire registration key. Secondly, run Colorist for Artists, and from the main (top) menu select Help and Activate Colorist. Then click on the Paste button and wait a few seconds for the registration process to complete.

Other Colorist Features

What is the difference between the Match Color and Image Color Gamut features?
Both features begin with loading an image file or pasting an image from the Windows clipboard. Common formats such as .BMP, .JPG, .GIF, .PNG and .TIFF are supported. In Match Color, one can then click on any part of that image, and Colorist will suugest artists' paint colors that match the selected color. Note that at least one paint brand must have been selected from the Match Color Options. Image Color Gamut shows the complete color gamut of the loaded image, displaying it in the same format as the visual color wheel, with both the wheel and a chroma-lightness matrix for each hue. Additionally, any chroma-lightness matrix can be viewed in Match Color. Therefore it is possible to determine what modern paint colors might be used to represent the original image.
Does image compression (as is used in JPG files) distort colors?
Yes, any image compression will have a slight effect on the image colors. Additionally, most images will have been captured by a camera or scanner, and there is normally color distortion arising from those processes. One need only compare images of a particular painting on Google Images to see the wide variations in colors that can occur in the copying process(es).
What is My Palette used for?
My Palette lets you add artists' paint colors to a visual color wheel. Colors can be added directly from lists on the My Palette page, or indirectly from the Match Color page. Once 3 or more colors have been added, a bounding polygon representing the available color gamut is drawn. This polygon shows the color chroma limits for each hue of the color wheel. As one traverses the wheel, the chroma-lightness matriix also shows the chroma approximate chroma bounds for each hue.
Why makes Image Color Gamut so useful?
With Image Color Gamut one can determine the color gamut (range) used by an artist to create a painting. As stated by James Gurney in Color and Light, "Good color comes from not just what you include in a composition but from what you leave out of it." For proof of this, see Some Color Gamuts of Famous Paintings. One can go further. By transferring the chroma-lightness matrix of a selected hue to Match Color, one can even determine what modern artists' paints could be used to achieve a similar effect.
What is A Better Match?
A Better Match is a means by which artists and designers can help refine how paint colors are displayed in Colorist. Those paint colors are mostly copied directly from online color charts provided by paint manufacturers. In some cases, some of those colors may not be as close to the actual paint color as might be desired. A Better Match provided two ways of voluntarily helping Cravecolor provide the best match possible.
