New API V3.0: Get our API at a special price. Get it now. Get more detailed color conversion results - perfect for web projects, plugins, internal tools or SaaS applications. Valid from 2025-10-21 up to and including 2025-11-21 (23:59 CET)
First enter the color code to find the conversion and the best matching colors. After that, you can create palettes by clicking on and download color samples.
If you want to translate a digital web colour into a real-world paint, you can convert from HEX to Sherwin-Williams®. The six-digit HEX code is matched to the closest Sherwin-Williams paint shade.
The conversion from HEX to SW is ideal for designers, architects, and brand managers who need colour consistency between digital and physical environments.
qConv analyses your HEX code, converts it to LAB, and compares it against the Sherwin-Williams® database to find the visually closest match.
How does it work?
During the HEX to Sherwin-Williams conversion, the HEX value is converted to RGB and then LAB. qConv identifies the Sherwin-Williams shade with the smallest Delta-E difference.
Example results: SW 7008 Alabaster or SW 6868 Real Red. qConv also shows colour deviations and alternative tones.
This HEX to SW conversion ensures precise translation of web colours into real paints and finishes.
Example & Application
Example: #F7E7CE ≈ SW 6385 Dover White. qConv instantly displays this HEX-SW conversion with LAB and RGB values.
Tip: Use qConv early in your project to align digital brand colours with physical environments.
* Note:
qConv.com searches for the next matching color from the selected color palette. In most cases, there will be minimal or apparent color differences because there is not an exact match for every color.
The hexadecimal color system is one of the most widely used methods for representing colors in digital media. It combines the three primary colors — Red, Green, and Blue — and expresses their values using hexadecimal notation. Each color component is represented by two characters, forming a six-digit code such as #FF5733.
The first two digits represent red, the middle two green, and the last two blue. The range of each pair goes from 00 to FF, corresponding to 0–255 in decimal values. With this structure, there are a total of 16,777,216 possible hexadecimal colors, covering nearly the full visible RGB color range.
Usage
Hexadecimal color codes are the standard for web design, front-end development, and digital branding. They are supported in HTML, CSS, SVG, and nearly all design applications. HEX values are compact, easy to read, and ideal for defining precise colors in digital interfaces, animations, and style sheets.
In professional design workflows, HEX values are often used alongside RGB or HSL to ensure consistency across screens. Designers can also use HEX-to-RGB conversions to fine-tune colors for print simulations or cross-platform visual harmony.
Tips for Designers & Developers
When creating color palettes, group HEX values that share visual harmony — for instance, complementary or analogous combinations. Use lowercase HEX (e.g. #a1b2c3) for better readability and code consistency.
With qConv, you can instantly convert HEX colors into RGB, CMYK, or Pantone® equivalents, generate gradients, or explore related shades and tints. Perfect for designers and developers seeking pixel-perfect color accuracy.
The Sherwin-Williams® color system is one of the world’s most comprehensive professional paint collections, featuring more than 1,700 standardized colors used in architecture, interior design, and industrial coatings. Each color is precisely defined by a unique code, ensuring consistent application across different materials and projects.
Sherwin-Williams® paints are formulated for both aesthetic excellence and long-term durability. The brand offers digital color libraries that integrate seamlessly with professional design software, enabling accurate color visualization and matching across print, digital, and real-world surfaces.
Usage
Sherwin-Williams® colors are widely used in residential and commercial architecture, product manufacturing, and brand design. They play a key role in creating mood, atmosphere, and identity within spaces. The color library is available through physical swatches, color fan decks, and digital databases, making it accessible for both design professionals and homeowners.
The system also supports industrial coatings and protective paints, ensuring that the same color tone can be achieved across metals, plastics, and building materials.
Tips for Designers & Architects
When specifying Sherwin-Williams® colors, always verify the finish — matte, satin, semi-gloss, or gloss — as surface texture affects how the color is perceived. For digital projects, qConv allows you to convert any Sherwin-Williams® color into RGB, HEX, or CMYK formats for accurate visualization and brand consistency.
Use qConv to explore matching and complementary colors across Sherwin-Williams®, Pantone®, and RAL® systems to ensure seamless cross-media integration.
