'''Colors''' are represented in LabVIEW by an unsigned 32-bit integer. The integer is of the hexadecimal form 0x00RRGGBB, where RR, GG, and BB represent the red, green, and blue components of the color, respectively.
{{Underconstruction}}


== Special cases ==
LabVIEW represents colors as unsigned 32-bit integers in the form <code>0x00RRGGBB</code>, where <code>RR</code>, <code>GG</code>, and <code>BB</code> represent the ''red'', ''green'', and ''blue'' color components, respectively. The upper byte (<code>00</code>) is reserved for special colors like [[#Transparency|Transparent]] and [[#System Colors|System colors]] in which the least significant bit is set to <code>1</code>.


LabVIEW uses the upper byte (00) for special colors, normally this byte is used for transparency so using these color values in a different program might give odd results.
== Transparency ==


== Transparent  ==
The "transparent" color has the value <code>0x01000000</code>. Elements with this color appear fully transparent.


Transparent has a color value 0x01000000 the last bit of the transparency byte is high, this can be used to create 'holes' controls:
It is <u>not</u> possible to set a semi-transparent color to individual elements in LabVIEW<ref>[https://lavag.org/topic/5563-control-transparency/ Control Transparency] (LAVA)</ref>.


== System Background  ==
== System Colors ==
 
This color turns the background into the background of the front-panel/block diagram. It's value is 0x01000037, special details: [[System Label|System_Label]].

LabVIEW has additional colors that are used for specific elements, like the tank fill color, here's an overview of these colors and their LabVIEW color value, these are not stored with a special value, the following lists the default values for these colors. LabVIEW defines 15 colors per default, but has support for 3 additional colors.  
LabVIEW provides slots for up to 18 user colors that can be set to custom values. By default, 15 colors are pre-defined.

=== Custom user colors ===
 
User colors can be set in the options dialog under ''Tools > Options... > Environment > Custom Colors...'':
 
[[File:ColorAdjustUser.png]]


To adjust (or add) colors use the LabVIEW options Dialog. In LabVIEW 2009 the colors can be set in the ''Environment'' section.
== Environment colors ==


A special dialog is available for the 18 supported colors:
When the least significant bit of the upper byte is set to <code>1</code>, LabVIEW returns environment colors. For example [[#Transparency|transparent]] (<code>0x01000000</code>). These environment colors are mostly undocumented. However, some resources are available<ref>[http://www.ni.com/example/29125/en/ Using System Colors] (NI Example Programs)</ref><ref>[https://labviewcvi.wordpress.com/2010/05/11/“secret”-labview-system-colors/ "Secret" LabVIEW System Colors] (Vision Technologies)</ref> which list following colors:

LabVIEW represents colors as unsigned 32-bit integers in the form 0x00RRGGBB, where RR, GG, and BB represent the red, green, and blue color components, respectively. The upper byte (00) is reserved for special colors like Transparent and System colors in which the least significant bit is set to 1.

Transparency

The "transparent" color has the value 0x01000000. Elements with this color appear fully transparent.

It is not possible to set a semi-transparent color to individual elements in LabVIEW[1].

System Colors

What are the system colors on Linux and macOS?

LabVIEW provides six system colors that change depending on the selected color theme of the Operating System[2]:

Name Value
LabVIEW Windows[3] LabVIEW Windows[3]
Panel & Object COLOR_BTNFACE (15) 0x01000016 0x00F0F0F0
Panel & Object Text COLOR_BTNTEXT (18) 0x01000006 0x00000000
Window COLOR_WINDOW (5) 0x0100000A 0x00FFFFFF
Window Text COLOR_WINDOWTEXT (8) 0x0100000C 0x00000000
Highlight COLOR_HIGHLIGHT (13) 0x01000008 0x000078D7
Highlight Text COLOR_HIGHLIGHTTEXT (14) 0x01000009 0x00FFFFFF

There's a VI on ni.com that demonstrates all the LabVIEW system colors, which includes many more than can be selected from the color picker dialog: [1]

Change system colors on Windows 10

Windows 10 has no built-in dialog to change system colors[4]. The color values, however, can still be modified directly in the Registry under HKEY_CURRENT_USER\Control Panel\Colors (requires reboot) or via SetSysColor[5] (doesn't require reboot).

Reads a system color using GetSysColor[3]
Sets a system color using SetSysColor[5]

User colors

LabVIEW provides slots for up to 18 user colors that can be set to custom values. By default, 15 colors are pre-defined.

Name Value
3D object 0x00BCBCBC
Control background 0x00FAFAFA
Indicator background 0x00D2D2D2
3D Active object 0x00969696
Text 0x00000000
Led On 0x0064FF00
Led Off 0x001E4B00
Thermometer Fill 0x00FF0000
Slide Fill 0x000041DC
Slide Housing 0x006D6D83
Tank Fill 0x000041DC
Tank Housing 0x00A9B3CB
Classic Object 0x00B3B3B3
Classic Slide Object 0x003399FF
Refnum Wire 0x00007F7F

These color's are stored in the LabVIEW configuration file with the token colorUserItem

Custom user colors

User colors can be set in the options dialog under Tools > Options... > Environment > Custom Colors...:

Environment colors

When the least significant bit of the upper byte is set to 1, LabVIEW returns environment colors. For example transparent (0x01000000). These environment colors are mostly undocumented. However, some resources are available[6][7] which list following colors:

Color Value Description
