qb64/internal/help/_RGB32.md

The [_RGB32](_RGB32) function returns the 32-bit *RGBA* color value with specified red, green and blue component intensities and optional alpha.

## Syntax

*Original syntax*:

> color32value~& = [_RGB32](_RGB32)(red&, green&, blue&)

*Alternative Syntax 2*:

> color32value~& = [_RGB32](_RGB32)(red&, green&, blue&, alpha&)

*Alternative Syntax 3*:

> color32value~& = [_RGB32](_RGB32)(intensity&, alpha&)

*Alternative Syntax 4*:

> color32value~& = [_RGB32](_RGB32)(intensity&)

## Parameter(s)

* red& specifies the red [LONG](LONG) component intensity from 0 to 255.
* green& specifies the green [LONG](LONG) component intensity from 0 to 255.
* blue& specifies the blue [LONG](LONG) component intensity from 0 to 255.
* alpha& specifies the alpha [LONG](LONG) component from 0 to 255.
* intensity& specifies the red, green and blue [LONG](LONG) components intensity from 0 to 255 simultaneously, to generate a shade of gray.

## Description

* The value returned is always a 32-bit [_UNSIGNED](_UNSIGNED) [LONG](LONG) color value, as is the [POINT](POINT) value. 
* **Return variable types must be [_UNSIGNED](_UNSIGNED) [LONG](LONG) or [LONG](LONG), otherwise resulting color may lose the [_BLUE](_BLUE) value.**
* Parameter values outside of the 0 to 255 range are clipped.
* Returns [LONG](LONG) 32 bit hexadecimal values from **&H00000000** to **&HFFFFFFFF**.
* When [LONG](LONG) values are [PUT](PUT) to file, the ARGB values become BGRA. Use [LEFT$](LEFT$)([MKL$](MKL$)(color32value~&), 3) to place 3 colors.
* **NOTE: Default 32-bit backgrounds are clear black or [_RGB32](_RGB32)(0, 0). Use [CLS](CLS) to make the black opaque.**

## Availability

* Alternative syntax available with version 1.3 and up.

## Example(s)

Converting the color port RGB intensity palette values 0 to 63 to 32 bit hexadecimal values. 

```vb

SCREEN 12
DIM hex32$(15)
FOR attribute = 1 TO 15
  OUT &H3C7, attribute      'set color attribute to read
  red = INP(&H3C9) * 4      'multiply by 4 to convert intensity to 0 to 255 RGB values
  grn = INP(&H3C9) * 4
  blu = INP(&H3C9) * 4
  hex32$(attribute) = "&H" + HEX$(_RGB32(red, grn, blu))   'always returns the 32 bit value
  COLOR attribute
  PRINT "COLOR" + STR$(_RGB(red, grn, blu)) + " = " + hex32$(attribute)  'closest attribute
NEXT 

```

```text

COLOR 1 = &HFF0000A8
COLOR 2 = &HFF00A800
COLOR 3 = &HFF00A8A8
COLOR 4 = &HFFA80000
COLOR 5 = &HFFA800A8
COLOR 6 = &HFFA85400
COLOR 7 = &HFFA8A8A8
COLOR 8 = &HFF545454
COLOR 9 = &HFF5454FC
COLOR 10 = &HFF54FC54
COLOR 11 = &HFF54FCFC
COLOR 12 = &HFFFC5454
COLOR 13 = &HFFFC54FC
COLOR 14 = &HFFFCFC54
COLOR 15 = &HFFFCFCFC

```

> *Note:* This procedure also shows how the returns from [_RGB](_RGB) and [_RGB32](_RGB32) differ in a non-32 bit screen mode.

Working with 32 bit colors.

```vb

SCREEN _NEWIMAGE(640, 480, 32)

CLS , _RGB32(0, 0, 128) 'deep blue background

LINE (100, 100)-(540, 380), _RGB(255, 0, 0), BF ' a red box
LINE (200, 200)-(440, 280), _RGB(0, 255, 0), BF ' a green box

SLEEP 'Just so we can see our pretty background before we print anything on it.

COLOR _RGB32(255, 255, 255), 0 'White on NO BACKGROUND

FOR i = 1 TO 10
    PRINT "This is just a whole bunch of happy nothing!  Happy World!!"
NEXT
PRINT: PRINT: PRINT:

COLOR 0, _RGB32(0, 0, 0) 'And here, we're going with NO COLOR text, with a BLACK background.
'Notice how this doesn't change the color on the screen at all, where the text is, but does toss a black background to it.

LOCATE , 15: PRINT "NOTICE HOW OUR 0 COLOR WORKS?"
PRINT
LOCATE , 15: PRINT "NEAT, HUH?"
SLEEP

Comparing the output of the new _RGB32 syntaxes (starting with version 1.3) and their equivalents in previous versions. 

```vb

SCREEN _NEWIMAGE(400, 400, 32)

COLOR _RGB32(255, 255, 255)
PRINT "White"
COLOR _RGB32(255)
PRINT "White, too, but with less typing"
PRINT

COLOR _RGB32(80, 80, 80)
PRINT "Dark gray"
COLOR _RGB32(80)
PRINT "Same gray, but with less typing"
PRINT

COLOR _RGBA32(255, 255, 255, 120)
PRINT "White with alpha of 120 (out of 255)"
COLOR _RGB32(255, 120)
PRINT "White with alpha of 120 - but with less typing"
PRINT

COLOR _RGBA32(255, 0, 255, 110)
PRINT "Magenta, 110 alpha"
COLOR _RGB32(255, 0, 255, 110)
PRINT "Magenta too, 110 alpha - but with less typing"
