Description

generate_rgb(exist_colors)[source]¶

Generate new color which oppositely by exist colors.

Parameters

exist_colors : list: List of existing colors in RGB format.

Returns

RGB integer values

Return type

List[int, int, int]

Usage example

import supervisely as sly

exist_colors = [[0, 0, 0], [128, 64, 255]]
color = sly.color.generate_rgb(exist_colors)
print(color)
# Output: [15, 138, 39]

hex2rgb(hex_value)[source]¶

Convert HEX RGB string to integer RGB format.

Parameters

hex_value : str: HEX RGB string.

Returns

RGB integer values

Return type

List[int, int, int]

Usage example

import supervisely as sly

hex_color = '#8040FF'
color = sly.color.hex2rgb(hex_color)
print(color)
# Output: [128, 64, 255]

random_rgb()[source]¶

Generate RGB color with fixed saturation and lightness.

Returns

RGB integer values

Return type

List[int, int, int]

Usage example

import supervisely as sly

color = sly.color.random_rgb()
print(color)
# Output: [138, 15, 123]

rgb2hex(color)[source]¶

Convert integer color format to HEX string.

Parameters

Return type

str

Usage example

import supervisely as sly

hex_color = sly.color.rgb2hex([128, 64, 255])
print(hex_color)
# Output: #8040FF

validate_channel_value(value)[source]¶

Generates ValueError if value not between 0 and 255.

Parameters

value : int: Input channel value.

Raises

ValueError if value not between 0 and 255.

Returns

None

Return type

NoneType
