Color: Difference between revisions

Revision as of 09:28, 16 November 2019

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

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]:
