Please check "RGB color definition" section within Upgrade Guide:
https://dev.opencascade.org/doc/overview/html/occt__upgrade.html#upgrade_750_srgb_color
https://dev.opencascade.org/index.php?q=node/1281

Use Quantity_TOC_sRGB instead of Quantity_TOC_RGB in case if your color picker returns values in non-linear sRGB color space.
