52 tools on the shelf

Every color tool, filed by the code in your hand

52 color tools sit on Toolexe. Most answer one narrow question. This page files each one by the code already in your hand.

A clean swatch on a monitor is not a promise about ink.

RGB and hex describe light added on a screen. CMYK describes ink on paper. The bright end of a monitor has no four-ink equal. HSV splits a color into hue, saturation, and value, the set to open when one knob should move and the others should stay. Pantone names are spot inks. A browser does not mix those inks. Converters on this shelf use a direct formula and skip the press profile. Treat the print figure as a first build. Proof the sheet before the argument.

Wrong converter, wrong number.

The diagonal is the same model, so no page sits there. Alpha lives only on HEX to RGBA. LAB and XYZ live only on the Color Space Converter.

Ten rails, 52 tools

The first five rails assume you walked in with a code. The last five assume you walked in with a job.

Hex in the clipboard

Six digits, or the three-digit shorthand. Eight digits carry alpha. Only HEX to RGBA reads the fourth pair.

An RGB triple

Out-of-range channels get clamped to 0 or 255. A value of 300 is not rejected.

A CMYK build

Percentages, not 0 to 255. A 100/100/100/100 build piles ink. Rich black is a different recipe, and this shelf does not pick one.

Hue, saturation, value

Value is not HSL lightness. The same hue at full value is not the color full HSL lightness would give you. The two scales split the color differently.

A Pantone code

Codes come from a public table. The rank is distance, not a licensed fan deck.

One box for every model

LAB and XYZ have no solo page. Kelvin has one page: a blackbody curve, not the warmth slider on a monitor.

A set, not a single swatch

Wheel math hands you a starting set. Your logo is a separate decision.

Change the color you have

Lighten and darken are not mirrors of one algorithm. Read the method name before you trust the hex.

Will the type still read

4.5 to 1 for body text at AA. 7 to 1 at AAA. Large text is allowed 3 to 1 at AA. Read which bar the page cites.

Brand, mood, other sites

Pulling colors off another homepage is research. Copying the brand needs permission this page does not grant.

Colliding names

Three pairs share a verb. They do not share a result.

Follow one orange past the screen

#C2410C is red 194, green 65, blue 12.

On white the contrast ratio is 5.18 to 1. Body text clears AA and misses AAA. On #1C1410 the ratio falls to 3.51 to 1, under the 4.5 to 1 body-text line. A close tint, #F4A28A on the same orange, scores 2.56 to 1. Fine as a shape. Not as a sentence. If the pair is for type, open the contrast checker before you ship.

Naive CMYK from #C2410C is 0, 66, 94, 24. Run the percentages back through the same formula and the RGB barely moves. The trap sits there. A matching screen after a round trip does not mean a coated sheet will match. If the brochure is already at the printer, open RGB to CMYK for the build, then argue from the shop proof.

HSV sits near 17 degrees, 94 percent saturation, 76 percent value. A 15 degree spin is a different orange. Use the hue shifter for the spin. The mixer blends two colors. Rotation is a different job.

Questions from the proofing table

Why does a round trip still look right on screen?

The converters use a direct formula. #C2410C becomes CMYK 0, 66, 94, 24 and converts back to almost the same RGB. A press profile clips colors the four inks never reach. The formula never applies the press profile, so a matching screen is not a matching sheet.

Is a Pantone name from these pages safe on a purchase order?

No. Matches are the nearest public names, ranked by distance. They are not a licensed Pantone library. Confirm the code on a physical fan under the light the job will use.

Body text passes AA and misses AAA. Ship the pair?

For normal body text, AA is 4.5 to 1 and AAA is 7 to 1. #C2410C on white is 5.18 to 1, so AA passes and AAA does not. On #1C1410 the ratio is 3.51 to 1, which fails body text. Large text is allowed a lower bar. Read the bar the page cites before you ship.

Which invert page flips a color?

Color Inverter flips one color by RGB, HSL, or luminance. Color Inversion offers an RGB complement, a hue rotation, or a luminance flip. The three results differ. Pick the method, not the shorter name.

Does a color I type get uploaded?

No. The math runs in the browser. These color pages do not send the value to Toolexe.
