	The standard luminance model is a visual model which attempts to map colors to human perceptions of brightness. This is the model use for making lithophanes and as such was the first model used to build HueForge meshes. The default HueForge Luminance mode is [[#\|Combo Luminance]] which is a mixture between Standard Luminance and [[#Max Channel Luminance]] but with the weight set to 100% Standard Luminance on the [[#\|Combo Slider]]. In this mode, colors with overlapping luminance values will be impossible to separate, but if your image is shades of the same colors (fire for instance) or grayscale, it will work beautifully. There are still a large number of images which work well in Standard mode.		The standard luminance model is a visual model which attempts to map colors to human perceptions of brightness.

	~~Currently~~ in ~~Beta release (Commercial License holders only)~~, Color Match effectively lets users create their own "Luminance" function that is defined by color. When Color Match is selected, a new ~~Color Core~~ (called the Mesh Core) ~~will be~~ created. If this is the first time, the filaments on the Color Core will be copied onto the Mesh Core.		Recently released in version 0.8.0, Color Match effectively lets users create their own "Luminance" function that is defined by color. When Color Match is selected, a new core (called the [[#\|Mesh Core]]) is created. If this is the first time, the filaments on the Color Core will be copied onto the Mesh Core.

	Toggling [[#~~Shown Colors~~\|Shown Colors]] ~~will switch~~ which Core is being used to predict mesh visualization (the left side image). This allows a user to use the Mesh Core to create a custom luminance stack by placing colors on the mesh core (either filaments or colors pulled from the image itself using Ctrl+Left-Click and Drag (or Command+Left-Click on MacOS - you must release Cmd after the drag has started to allow dropping)). HueForge will then go pixel-by-pixel and find the best color match on the Mesh Core and make that pixel location the correct height to show that color when printed. This process will build a mesh that can then be colored by switching Shown Colors to the Color Core and applying Filaments. It is not recommended to apply [[#Image Colors]] to the Color Core since they do not represent real filaments and you will not be able to print with them.

It is not recommended to apply [[#Image Colors]] to the Color Core since they do not represent real filaments and you will not be able to print with them.

	Color Match allows for many more "Color Bins" than [[#~~Color Aware~~\|Color Aware]] but it can still be difficult to distinguish all colors. Highlights in particular often bleed between color regions on the Mesh Core. Also the user should be aware that human color perception is extremely contextual and if you are having a hard time making a color match with filaments, you should grab the [[#~~Image Color~~\|Image Color]] and you will often be surprised by what the actual color is.

	In Color Match, the [[#\|Combo Slider]] allows the user to add an upward or downward weighing on color matching. Values above 0.5 will weight matching upwards in the Mesh Core, and values below 0.5 ~~will weight~~ them downwards. This weighting is for all colors.

	Color Aware is a [[#Luminance Mode]] that splits the HueForge mesh into 3 sections by "color". (See [[Color_Aware]] for a basic How To guide) The colors are defined by the RGB color channels red, green, and blue. Color is picked by which color channel has the maximum value. Ties go to red, and if [[#Tolerance]] is 0, grayscale will go into blue unless there is a [[#Color Shift]]. This lets users separate color regions in images by color though sometimes the groupings are not ideal for the image. For instance yellow is in the red bucket, but often conflicts with skin tones or needs to blend smoothly with greens for leaves/plants.

	Using the CA Presets can also allow users to effectively remove one of the three ranges from the image when your image is primarily just two colors, though this is currently a byproduct of applying specific settings and is not a true removal of the third color space.

	In [[#Standard Luminance\|Standard Luminance]] mode, filaments are blended "down" to darker base layers (most commonly black). Blending up reverses this and puts the lighter colors at the bottom and the darker color at the top. This generally requires either a high TD dark shade, or multiple shades of a color to allow smooth color blending. The benefit is the black layer is generally shared with the next section and there will not be any white lip around the base of the next layer (see [{#Rebasing\|Rebasing]]).

	This is the traditional way of using HueForge. Darker colors on the bottom with the lighter colors on the top. Your blending is always referencing the colors below the current layer. The benefit of this mode is that darker colors tend to have lower [[#Transmission Distance (TD)]] and do not blend well, where brighter colors are available in higher TDs and can be blended providing shadows. This makes the filament requirements for blending much simpler. The drawback is primarily in modes like Color Pop and Color Aware. Since each section is ~~it's~~ own HueForge, the top of each section often has a white which will show on the edges of the print below the black of the next section.
