DESCRIPTION: This software is intended for use by modellers who wish to experiment with mixing paint (virtually) to match needed colours. See section USAGE below for more details. STATUS: This software is still under development and is only Beta standard at this time. REQUIREMENTS: Requires rustc 1.26.2 or later. INSTALLATION: It is NOT necessary to install this software in order to use it. All that is necessary is for the ./.target/release and/or ./.target/debug (as appropriate) to be in the user's PATH environment variable. USAGE: The software's GUI (mcmmtk_rs) has 2 selectable components: 1. The Paint Mixer is the component that (once the user has specified a colour to be matched and selected some paints for use) enables the modeller to mix paints by specifying the number of "parts" of each paint to be used in mixing a colour to match the specified colour. This mixed colour can then be saved to a list of mixed colours (along with notes about its intended use). When the modeller has finished mixing the colours that they require they may print out a report to be used as a reference while painting the model for which the colours were mixed. 2. The Paint Series/Standards Editor is the component that enables the modeller create/modify sets of paints for use in the mixer. The recommended method is to produce a "sampler" of the actual paints to be used on a suitable medium (preferably airbrushed), take a digital photograph (or scan) and then cut and paste from that photograph into the paint series editor where its buttons can be used to match the colour. A Colour Sample Viewer is included as part of the editor. An example colour sampler file has been added and should be loaded by the viewer the first time it is launched (and after that it should remember the last file used). NB although manufacturer's digital colour charts can be used for a sample source they are not necessarily accurate as they were NOT produced with this use in mind and colours are frequently modified to accentuate the difference between colours. NB the provided sample is hand painted and should make it clear why an air brushed version is preferred. PAINT SERIES: At this time, the only paint series data included in the distribution is for an imaginary set of paints known as the "Ideal Paint Colours Series" which features six colours equally spaced around the colour circle (at maximim chroma) together with black and white. This series should be automatically included in the mixer's "Paint Colour Series"->Open menu when it is run for the first time. Although of no real use in practice this set of paints is useful for assessing the Mixer's potential and, more importantly, learning how to mix paints. If it existed it would be possible to match any colour with this set of paints (but unfortunately it's only imaginery). PAINT STANDARDS: At this time, the only paint standards data included in the distribution are for US Federal Standard 595C and British Standard 381C. Although all care has been taken in the preparation of this data, no guarantee as to its accuracy is made (caveat emptor). INTERNATIONALIZATION: None.
