Pixel

This function block creates a single custom color pixel using three sliders for Blue, Green and Red channel values. Use it when you need a color value (BGR tuple) as an input for other blocks or to build simple images.

📥 Inputs

This function block does not have any inputs.

📤 Outputs

(Blue, Green, Red) This output is a color tuple with integer channel values in BGR order (each 0–255). It can be used wherever a pixel or color value is required.

🕹️ Controls

Blue Value Slider to set blue channel (0–255) Green Value Slider to set green channel (0–255) Red Value Slider to set red channel (0–255)

🎨 Features

• Live adjustable sliders for each color channel for quick color selection.

• Produces a ready-to-use BGR color tuple for other blocks.

• Compact and simple UI for picking colors without external tools.

📝 Usage Instructions

1. Adjust the Blue Value, Green Value, and Red Value sliders to choose your color.

2. Connect the (Blue, Green, Red) output to any block that accepts a pixel/color or uses a mask/color parameter.

📊 Evaluation

When evaluated, the block returns a single tuple representing the selected color in BGR order. The value updates as you change the sliders.

💡 Tips and Tricks

• Combine with Make Image to create a solid color image quickly (use the selected color as the fill color).

• Use with Show Image to preview the resulting image or color-filled canvas.

• Use the color tuple as Mask Color input in RGB Mask or as color input for RGB Set to apply or visualize color-based operations.

• Save example palettes by connecting resulting images to Image Logger or Image Write for later reuse.

Suggested block combinations:

• Pixel → Make Image → Show Image

• Pixel → RGB Mask (as Mask Color) → further processing

• Pixel → RGB Set or Merge Channels when constructing or altering images

🛠️ Troubleshooting

• Unexpected color in results: remember the output ordering is BGR (Blue first). If a downstream block expects RGB, swap channels or use blocks that accept RGB/BGR appropriately.

• No effect on image: ensure the downstream block actually accepts a color or pixel tuple (check the target block's expected inputs).
